Abstract:
1. A magnetic tape drive including a head unit, the head unit comprising: a plurality of recording heads for recording data on a magnetic tape, the recording heads being aligned in a width direction of the magnetic tape, with adjacent recording heads having different azimuth angles; a plurality of reproducing heads for performing a readout of data from the magnetic tape, each reproducing head being disposed downstream in a tape travel direction of a corresponding recording head and having the same azimuth angle as the azimuth angle of the corresponding recording head; and a servo head for performing a readout of a servo signal recorded on the magnetic tape for a tracking control of the head unit, wherein the head unit further comprises sub-reproducing heads disposed on both sides of each reproducing head in the width direction of the magnetic tape, and the lengths and azimuth angles of the sub-reproducing heads are the same as the lengths and azimuth angles of the respective reproducing heads.
