Abstract
Write splicing for a helical scan tape drive (30) involves, upon occurrence of a predetermined condition such as a buffer low condition, recording an indication of a tape transport transition (ITTT) on tape (31) and then recording dummy helical stripes (DSd1-DSdn) having deviant form as the magnetic tape is decelerated to a stop. After the predetermined condition is overcome, further deviant, dummy stripes (DSa1-DSan) are recorded as the tape is accelerated back to nominal tape transport speed. At the nominal tape transport speed, non-deviant stripes (S2) containing user data are again recorded on tape. A distance separating a first set of stripes �S1! (recorded prior to the occurrence of the predetermined condition) and a second set of stripes �S2! (recorded upon again attaining the nominal tape transport speed) is an integer multiple of the track pitch (P) of a non-deviant stripe. The write splice is thus performed without reversing the direction of tape transport.
