| Abstract(in English) | Optical disk systems have advantages exceeding video-cassette recorders for broadcasting because they provide excellent random access, reliability and archiving performance. However, the transfer data rates of optical disks are inadequate for use in broadcasting applications. An optical disk medium, servo system and signal processing were developed for a 200-Mbps read/write system with two optical heads that was aimed at achieving HDTV newsgathering. Furthermore we developed Original disk format (ODF) such that a new high-speed file format which has two new characteristics for recording HDTV. One is guarantee of the minimum length of extent and another is division of the recording areas for the files and the directories. Our high-speed optical disk emulator proved that ODF is indispensable to achieve a consecutive data transfer rate of more than 200 Mbps per head. |
