Digitalizing image such as television broadcasting, the video recorder which records to DVD. One kind of video deck which uses DVD for the record media in place of the videotape.

You use the record media of DVD-R and DVD-RAM, etc if standard mode of the same type as DVD-Video approximately 2 hours (148 minutes) you can record animated picture. A higher bulk compressibility (however low picture quality) there are also some which correspond to the record time of time with 2 layer record media of thing and DVD-R DL etc whose with mode long haul record of 10 times is possible from 2 times.

But as for the basic using the same as the normal video deck, while the function which searches the program which we would like to see as the function which utilizes the feature of the random accessible digital media, at instant and, videotaping while the function which plays back another program, videotaping the function which from first can play back that program (“you chase and so on it is called playback”) are.

The device which removes the soiling of the lens which is inside optical driving of CD drive and DVD drive etc. The wet process which utilizes the clearing solvent there are two types of dry process which is not utilized.

Optical drive does the reading and entry of the data by irradiating the laser to the disk surface. It does lighting from the lens which is built in to the head, but while the long period of time having used, the lens becoming dirty and/or the dust being attached, there are times when the laser receives adverse effect. Removing the soiling of the lens, those where just it tries to be able to do playback and entry are the lens cleaner.

One of the connector form which is used with the DVI interface which connects the computer and display. Sending and receiving only the digital signal of TMDS system it is possible to do.

“DVI-D single link” of 23 pins which 1 can transmit TMDS link and, there are 2 types “of DVI-D dual link” of 29 pins which 2 can transmit TMDS link. To UXGA (1600×1200) it can correspond with single link, but in order to correspond to the resolution which exceeds this, dual link is needed. The connector of DVI-D from side of the terminal of 23/29 pins of DVI-I, “*” has become the form which excludes the terminal of 5 pins for the analog which does shape, DVI-I there is compatibility.
