Abstract
The tape drive control unit administers both computer data and video data that is stored on the same type of data storage media. This is accomplished by determining, when a magnetic tape is mounted in the tape drive, the format that is used to store the data on the magnetic tape media. In the case of video data, the data is directly written on to the magnetic tape media, while for computer data, a header is interposed between a leader portion of the magnetic tape on the 3480-type magnetic tape cartridge and the remainder of the magnetic tape contained therein.
