Title: A new servo method using servo layer and transverse MR head for submicron track servo on hard computer disks
Abstract: A disk with a data, servo and isolation layer has been fabricated with the data layer magnetized along the circumferential direction. The servo layer was recorded with servo pattern magnetized along the radial direction. A continuous servo signal is obtained and the servo does not occupy any data area. In this new method, the servo and data bits can share media surface area on the disk without interference. Track following on 0.7 μm tracks has been demonstrated using the new servo method on longitudinal rigid disks.
