Method for determining servo track pair position and longitudinal tape position for a tape using dedicated servo format

摘要

Servo track pair position and longitudinal tape position are determined for a tape using dedicated servo format. The tape includes at least one set of data tracks and dedicated servo tracks wherein adjacent servo tracks are defined by longitudinal lines through the edges of erased or non-recorded tape portions. The information about servo track pair numbers and/or servo sample numbers is recorded into portions of the tape and is decoded and read back together with signals from the servo track. The information is recorded in a digital manner by using a digital block format of data blocks requiring fewer bytes per block than a data block provided on the data tracks. If information about longitudinal tape position is not required, information may be recorded in an analog manner using a fixed set of predetermined frequencies.
