ABSTRACT:
A multi-track magnetic recording tape and a corresponding method for providing an early warning of end-of-tape conditions and an indication of load-point conditions, without the use of inter-track markers. The recording tracks are divided into two sets located on separate halves of the tape, and the sets of tracks are longitudinally offset with respect to each other, to provide a half-width unrecordable region at each end of the tape. A tape marker is located in each of the unrecordable regions, each marker serving as a load-point marker for use with one set of tracks, and as an early-warning marker for use with the other set of tracks.
