MAGNETIC RECORDING AND REPRODUCTION APPARATUS FOR DATA PROCESSING UNIT AND MAGNETIC TAPE FOR USE IN SUCH APPARATUS

摘要

A magnetic recording and reproduction apparatus for a data processing unit is disclosed. The apparatus includes a plurality of magnetic heads, formed integrally by a thinfilm-forming technology, and a magnetic tape. The magnetic tape has a plurality of recording tracks corresponding to a plurality of independent data. The recording tracks are arranged in parallel to a moving direction of the magnetic tape, and share the same starting position. The plurality of magnetic heads are arranged in parallel to a width direction of the magnetic tape so as to correspond to the recording tracks in a one-to-one correspondence, and are fixed at the starting position of the recording tracks. The magnetic tape is moved in a direction in which the starting position is away from the magnetic heads for data recording onto the magnetic tape and for data reproduction from the magnetic tape. Further, the magnetic tape is controlled to automatically move in an opposite direction to the previous direction until the starting position reaches the position of the magnetic heads in response to the end of either data recording or data reproduction. Thus, the starting position of the recording tracks corresponds exactly to the position of the magnetic heads for the start of data recording and for the start of data reproduction.
