Tape width measurements

摘要

A tape drive is disclosed. The tape drive determines a current tape width and writes data to the tape as well as the current tape width. The tape width written to the tape is associated with the data. When reading data from a tape the tape drive reads the stored tape width and adjusts the current tape width to match the stored tape width before reading the data associated with the stored tape width.

主权项

1. A tape drive, comprising:
a first and a second servo element to read a number of azimuthally sloped transitions on a first and a second servo band on a tape traveling in a first direction; a servo processor to calculate a current tape width by determining a distance between the first and second servo bands; a tape tensioning system to adjust the current tape width to a predetermined tape width before writing information to the tape; a controller to write information to the tape; the controller writing data to the tape and writing the current tape width onto the tape, wherein the current tape width is associated to the data.
