ABSTRACT:
A tape apparatus for recording and reproducing on a magnetic tape longitudinally disposed blocks of parallel multiple tracks of predetermined length. The apparatus includes a rotating drum and means for presenting predetermined lengths of tape to said drum. The rotating drum supports the tape upon a self-generating air bearing. Magnetic heads extend through the drum to rotate with the drum and cooperate with the tape to record and reproduce longitudinal tracks on the tape. The heads are movable longitudinally along the drum to record a plurality of adjacent longitudinal tracks. The tape is maintained under predetermined tension to maintain a constant air cushion between the tape and drum.
