TILED PARTITIONING FOR MAGNETIC TAPE RECORDING

摘要

An apparatus for recording information on a magnetic recording tape. A head positioning motor (144) vertically positions a head according to signals from a positioning motor drive (158). A capstan controls motor (150) controls the motion of the tape according to signals from a capstans driver (156). A control processor (130) controls the positioning of the head motor (144) and the capstan motor (150) to cause the head to interact with a particular portion of the tape. The control processor (130) uses partitions on the tape which are configured as rectangular collection of physical frames. The control processor further interacts with a partition directory or partition frame by two points on a diagonal of the tape. The control processor further receives information indicating the type of tape device. The control processor further interacts with early warning markers recorded on the tape.
