Positioning separate read and write heads in a disk file. |
摘要 |
<p>A method of positioning separate read and write heads in a disk file compensates for misalignment of the heads when reading and writing data on the disk. Two sets of servo information are generated for each track on the disk. These sets are radially displaced with respect to each other by a distance equal to the respective misalignments between the read and write heads at each respective track. One set is generated by the write head. The other set is generated by the write head while the read head is aligned with said one set. Thereafter, to write data on a selected track, the read head is first aligned with said one set of servo information and then data is written on said track with the write head. To read data on a selected track, the read head is aligned to said other set of servo information and then the data is read by said read head.</p> |
