Hitachi, Matsusita and SONY have proposed the consumer-use VTR format for the 1125line/60Hz Japanese Hi-Vison system, and announced the specifications of this VTR. In these specifications, we adopted a base-band recording method which dose not require any band compression. In making this adoption we took into consideration two typical uses, recording of broadcasted signals and playback of software tapes. And the width (1/2inch) and the thickness(13um) of the tape enable 3 hours recording with almost the same size cassette as is being by consumers at present.

We have developed a new analog signal processor IC for 2X DVD playback system. In this IC, frequency characteristics of equalizer can be adapted to playback rate by micro-processor. Tracking error signal can be generated by 3 methods-DPD (Differential Phase Ditection) method, 3 spot method and push-pull method. DPD block can remove offset caused by object lens shift, regardless of pit depth.
