    摘要: Disclosed is an apparatus and method for correcting for track misregistration when a slider or head assembly contains a separate read element (40) and write element (42). Basically, the offset is determined at a first position and at a second position of the actuator arm (48) assembly. From these offsets a constant and a multiplier are determined for determining an offset as a function of the cylinder location. Also disclosed is a method and apparatus for minimizing distance traveled to prevent misregistration when repositioning between the read element and a write element. The read element is intentionally offset from the write element at an angle so as to minimize the distance traveled across the disk.

    摘要: A display work station has a rotatable CRT display 18 for presenting data in a vertical and horizontal orientation. The orientation of the CRT display 18 causes activation of the switches that control the electronic logic to modify the addressing sequence of data retrieved from a refresh memory so that the data are presented properly on the CRT face.

    摘要: A phase modulated servo method and apparatus are provided for use in a disk file. The disk file includes at least one disk mounted for rotation about an axis and the disk has at least one disk surface for storing data. At a predefined location of the disk surface a series of servo tracks of a predetermined high gain servo pattern are written. The predetermined high gain servo pattern includes 360° phase difference information within each data cylinder. The servo tracks are detected for identifying servo phase information.
