Magnetic recording disk having a transition zone
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.
1 . A magnetic recording disk, comprising:
a first zone to store data;
a second zone adjacent to the first zone, the second zone having a surface to increase a fly height of a head greater than when the head is operating over the first zone; and
a third zone adjacent to the second zone in which to park the head thereabove.
2 . The magnetic recording disk of claim 1 , wherein the third zone is a load/unload zone.
3 . The magnetic recording disk of claim 31 , wherein the fly height is a distance between the first zone to store data and the head.
4 . A magnetic recording disk, comprising:
a first zone to store data;
a second zone adjacent to the first zone, the second zone comprising means to increase a fly height of a head greater than when the head is operating over the first zone; and
a third zone adjacent to the second zone in which to park the head thereabove.
5 . The magnetic recording disk of claim 4 , wherein the fly height is a distance between the first zone to store data and the head.
6 . A disk drive, comprising:
a slider comprising a Hall effect head or a head having a magneto-resistance read element; and
a magnetic recording disk comprising:
a first zone to store data;
a second zone adjacent to the first zone, the second zone having a surface to increase a fly height of the slider greater than when the slider is operated over the first zone; and
a third zone adjacent to the second zone in which to park the slider thereabove.
7 . The disk drive of claim 6 , wherein the third zone is a load/unload zone and wherein the slider is coupled to a suspension arm, the suspension arm configured to park the slider above the load/unload zone when the slider resides on a ramp.
8 . The disk drive of claim 6 , wherein the fly height is a distance between the first zone to store data and the head.
