About Card Reader

With the society development, card reader is also important for these like use the hdd to save they message, also the photograph guys. However we all know that the card reader support lots of card, but what the means of card reader, just reader card? Let me say to yours:

Most card reader function like as below: 1.Genuine & 100% breand new. 2.Super Speed USB 3.0 interface (also compatible with USB 2.0). 3.Supports SDXC Micro SDXC cards. 4.Transfer high-resolution images and video recordings to your computer faster and more efficiently. 5.Utilize the full speed potential of your memory cards. 6.USB powered (no external power or battery needed). 7.LED card insertion / data transfer activity indicator. 8.Operation System requirement: Window 98 SE/ ME/ 2000/ XP/ Vista/Windows 7, and Mac OS 10.4 or or higher versions.

There has different price for the DVD drive, the reason why is due to the speed(include writer and reader speed) and material(like plastic or metal) also the mould of design. that's my word for the price of different to DVD writer.

We all know the writer speed from 6x to 24x also has CD-R, CD-RW, DVD-RW, DVD+RW, DVD+RAW, DVD-R, DVD+R etc. However the reader speed also these disc style.

This blog just talk the general external DVD drive.

Standalone DVD recorders

When the standalone DVD recorder first appeared on the Japanese consumer market in 1999, these early units were very expensive, costing between $2500 and $4000 USD. However, as of early 2007, DVD recorders from notable brands are selling for US$200 or €150 and less, with even lower "street prices". Early units supported only DVD-RAM and DVD-R discs, but the more recent units can record to all major formats DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL and DVD+R DL. Some models now include mechanical hard disk drive-based digital video recorders (DVRs) to improve ease of use. Standalone DVD recorders generally have basic DVD authoring software built in; however, the appearance of the finished DVD is very basic and usually completely under the control of the unit.

Some believed that DVD recorders would supersede the VCR as the standard television-recording device; however as technology progresses, in 2009 Panasonic introduced the world's first Blu-ray Disc recorder which is capable of recording both DVDs and Blu-ray discs and features built in satellite HDTV tuners. A year later, Panasonic introduced further more Blu-ray disc recorders with terrestrial HDTV tuners.

DVD recorders have several technical advantages over VCRs, including:

Superior video and audio quality Easy-to-handle smaller form-factor disc media, and more durable than magnetic tape. Random access to video chapters without rewinding or fast-forwarding (serial access) Onscreen multilingual subtitles and labeling not available on VCRs Reduced playback wear and tear High-quality digital copying, with little or no generational quality loss Improved editing, at least on rewritable media Playlisting No risk of accidentally recording over existing content or unexpectedly running out of space during recording Easy to find recordings due to chapter menus Note: in addition Blu-ray disc recorders can record full high definition videos on BD-Rs and BD-REs.

It does have some disadvantages:[citation needed]

Slow initial access/load times due to the optical nature of the disc Limited rewritability on DVDRW(+RW) discs (typically around 1000). DVD-RAM is better suited for high frequency re-recording (around 100,000 rewrites) Relatively short life of the laser diodes (average of about 2 years depending on usage). However, an inconvenience exists in which DVDs recorded with DVD recorders in the standard DVD format must be finalized to view in other DVD players. (This disadvantage does not apply to discs recorded in the newer and more flexible Video recorder 'DVD-VR' format or the DVD+VR format - the later (but not the former) also being compatible with DVD players.) The implementation of MPEG-2 compression used on most standalone DVD recorders is required to compress the picture data in real time, producing results that may not be up to the standard of professionally rendered DVD video, which can take days to compress.

Standard definition VCR replacement DVD video recorders typically has a set of standard recording modes for fitting 1, 2, 4, 6, 8, 10 hr modes (XP, SP, LP, EP, SLP, SEP, respectively) on single layer 12cm discs (DVD5).[3] These modes are comparable to those found on VHS VCRs using standard 120-tapes, having SP, LP, SLP modes of 2,4,6 hr.

The United States converted its over-the-air television broadcasts to digital "ATSC" in June 2009. However this will have very limited impact in ending the need for DVD recorders to perform realtime MPEG-2 encoding or transcoding. The only setup where ATSC could conceivably eliminate MPEG-2 encoding/transcoding in a DVD recorder would be where an antenna is hooked directly into a DVD recorder that has an integrated ATSC tuner. Even then however, the DVD recorder will have to transcode the ATSC MPEG-2 into DVD-Video-compliant MPEG-2 if the ATSC MPEG-2 stream isn't already DVD-Video-compatible. This would require transcoding for all high-definition broadcasts and some if not all standard-definition broadcasts. The same general situation applies to digital cable service; only DVD recorders with integrated digital cable ("QAM") tuners can possibly avoid transcoding, and then only if the digital cable system is already sending a DVD-Video-compatible MPEG-2 stream, which again requires transcoding of all HD content and some if not all SD content. All other setups (digital cable box's analog outputs to DVD recorder, satellite box's analog outputs to DVD recorder, DVD recorder tuning and recording analog cable channels which are still permitted after 2/2009, etc.) usually always involve an analog step with MPEG-2 encoding being necessary inside the DVD recorder.

A number of manufacturers have combined DVD recorders with mechanical hard disk drive-based digital video recorders, allowing for recording to large fixed disks, and the ability to view these recordings off the hard disk at a later date.

In Japan, AVCREC recorders, which are able to record MPEG-2 or AVC high definition video from ISDB broadcast with or without re-encoding, get increasingly popular. Initially, AVCREC recorders use DVD recordable discs, but newer models are able to record onto Blu-ray discs as well onto hard disk drives.

China's top economic planner approves highway project

BEIJING, Aug. 19 (Xinhua) -- China's top economic planning body said on Friday that it had given approval for an expressway in northwest China's Gansu Province, which will improve public transportation infrastructure. The expressway will start from Jingtai County in the city of Baiyin, and end at Lanzhou Zhongchuan International Airport, stretching for 124 kilometers in total, according to a statement on the website of the National Development and Reform Commission. The project is expected to cost around 7.93 billion yuan (about 1.2 billion U.S. dollars). Central and local governments will be responsible for around 35 percent of the capital need for the project, while bank loans will cover the remainder. The project is in line with the country's Belt and Road Initiative and will help promote local economic and social development, the statement said.

DVD recorder

 A DVD recorder is an optical disc recorder that uses Optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as stand alone components for use in television studios or home theater systems.
As of March 1, 2007 all new tuner-equipped television devices manufactured or imported in the United States must include an ATSC tuner. The US Federal Communications Commission (FCC) has interpreted this rule broadly, including apparatus such as computers with TV tuner cards with video capture ability,videocassette recorders and standalone DVD recorders. NTSC DVD recorders are therefore undergoing a transformation, either adding a digital ATSC tuner or removing over-the-air broadcast television tuner capability entirely.[1] However these DVD recorders can still record analog audio andanalog video.Technical information

Detail of DVD-RW optics
Originally, DVD recorders supported one of three standards: DVD-RAM, DVD-RW (using DVD-VR), and DVD+RW (usingDVD+VR), none of which are directly compatible. As a general rule, however, most current DVD drives support both the + and - standards, while few support the DVD-RAM standard, which is not directly compatible with standard DVD drives.
Recording speed is generally denoted in values of X (similar to CD-ROM usage), where 1X in DVD usage is equal to 1.321 MB/s, roughly equivalent to a 9X CD-ROM. In practice, this is largely confined to computer-based DVD recorders, since standalone units generally record in real time, that is, 1X speed.
Recorders use a laser (usually 650 nm red) to read and write DVDs. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. The faster the writing speed is rated, the stronger the laser is. DVD burner lasers often peak at about 100-400 mW in continuous wave (some are pulsed). Some laser hobbyists have discovered ways to extract the laser diode from DVD burners and modify them to create laser apparatus that can cause burning.
