ARCUATE SCANNING TAPE DRIVE

摘要

2114721 9326005 PCTABS00028 A tape drive includes a rotary head assembly (1830) for recording and playing back a series of arcuate tracks (305, 306) on a moving tape (302) where the tracks are transverse to the longitudinal axis of the tape. The tape drive includes a servo mechanism (1860-1870) for correcting track misregistration by adjusting the position of the rotary head assembly with respect to the tape in response to servo information in the arcuate tracks. A close transducing engagement between the tape and the rotary head assembly is provided by creation of a low ambient pressure between the assembly and the tape when the assembly rotates.
