Tape head azimuth adjustment

摘要

The azimuth angle between a tape head and magnetic tape accessed by the tape head must be properly set in high areal information density magnetic tape drives. A frame for setting the azimuth angle includes a first portion rigidly attached to a base. The head is mounted in a carriage held by a second frame portion permitting the carriage to move in a transverse direction across the tape width. Flexures join the first and second frame portions and permit the second frame portion to be rotated a frame angle relative to the first frame portion. Each flexure is positioned such that, when the frame angle is at a preset value, the flexure is radially aligned with the azimuth axis. A drive is set between the frame first and second portions. The drive rotates the second portion relative to the first portion by deflecting the flexures, thereby changing the azimuth angle.
