Abstract
The present invention is a method and apparatus for positioning a magnetoresistive (MR) head relative to a storage medium in a storage device. The storage medium is mounted in the storage device to allow relative movement between the MR head and the storage medium. The storage medium includes servo information provided to induce a thermal response in the MR head. A controller controls the relative movement between the MR head and the storage medium using the thermal response induced in the MR head.
Claims23
A storage device, comprising:
- a magnetoresistive (MR) head;
- a storage medium mounted to allow relative movement between said MR head and said storage medium, said storage medium including servo information provided to induce a thermal response in said MR head;
- and
- a controller provided to control the relative movement between said MR head and said storage medium using said thermal response in said MR head.
A method of positioning a magnetoresistive (MR) head relative to a storage medium having servo information, the method comprising the steps of:
- inducing a thermal signal in said MR head with said servo information;
- and
- moving said MR head in response to said thermal signal.
