Plurality of disk away units, data recording/reproducing method and data format

摘要

Video data controllers and disk array units are connected with an independent input serial transmission line and an independent output serial transmission line. Data is serially transmitted between the video data controllers and the disk array units. Data of the video data controllers is sent with time slots assigned thereto. Data has a synchronous signal at the beginning thereof. The synchronous signal synchronizes with time slots. The synchronous signal is followed by commands/status and video data.
