Abstract: FIXED HEAD, DIRECT ACCESS STORAGE DEVICE A disk file employs a fixed magnetic head and a rotary magnetic disk that precesses about the axis of a drive motor. An escapement mechanism, that is coupled to the rotary spindle which supports the disk, is free to rotate about the motor axis, causing the disk to precess while the disk is rotating. Thus, there is relative radial movement between the precessing disk and the fixed head, enabling accessing to different data tracks.
