ABSTRACT:
A system for converting user data between a computer data format and an NTSC format allows a video tape recorder (VTR) to be used as a data storage system. A buffer organizes the user data into scan group data for data recording from a host computer to the VTR, and separates the scan group data into the user data for data playback from the VTR to the host. The system of the invention receives the scan group data from the buffer and converts the scan group data into the NTSC format video fields for recording by the VTR. The invention also converts the NTSC format video fields into the scan group data for playback of data from the VTR to the host.
