Servo patterns for patterned media |
摘要 |
Servo patterns for patterned media (1201,1202,1203,1208). The servo pattern includes specification of cylinder/track ID with and without a Gray code. The servo pattern space is minimized by the optimum usage of the islands (1204,1209). This is achieved by island allocation rules to take advantage of non-magnetic island. The island allocation also provides for easier lift-off. Logic is used to encode and decode the Gray code. Further, the Gray code is designed to stabilize the magnetic island (1204,1207)/ non-magnetic island (1205,1209) ratio to allow for easier manufacture.
