Abstract
A disk drive having a magnetic recording disk with a transition zone is described. A surface texture of the transition zone induces the head to fly at a greater height than when operating over a data zone, while transitioning the head to a landing zone to park.
Claims6
A method of operating a head over a disk, comprising:
- operating the head at a first height over a data zone of the disk with respect to a data zone surface during at least one of a read operation and a write operation;
- parking the head at a second height with respect to the data zone surface;
- and
- operating the head at a third height, with respect to the data zone surface, over a transition zone of the disk while transitioning the head to park, wherein the third height is greater than the first height, wherein the data zone includes a discrete track recording (DTR) patterned surface and the transition zone has a planar surface relative to the DTR patterned surface.
