Paper Abstract

A digital video disk recorder which can record noncompressed NTSC digital video signal and 4 channel digital audio signals for 32 minutes has been developed. Using (phi) 30 cm magneto-optical (MO) double-sided disk, 23 GB recording data capacity and 123 Mbps high recording bit rate were performed. In order to realize high density and large capacity recording, we have improved optical heads, recording media and others, especially we have developed the new recording method called CWL_CAV (Constant minimum Wave Length - Constant Angular Velocity.
