Abstract
A magnetic media that has at least one groove. The groove is created by a process that includes initially forming a temporary layer over a magnetic layer of the disk. One or more grooves are formed in the temporary and magnetic layers. The temporary layer is removed and a protective layer is formed over the magnetic layer and within the groove.
Claims11
A method for fabricating a magnetic media of a hard disk drive, comprising:
- providing a media that has a magnetic layer and a substrate;
- forming a temporary layer over the magnetic layer;
- forming a least one groove in the temporary and magnetic layers;
- removing the temporary layer;
- and,
- forming a protective layer over the magnetic layer and into the groove.
3 more elements
A magnetic media of a hard disk drive, comprising:
- a substrate;
- a magnetic layer adjacent to the substrate, said magnetic layer having at least one groove with a depth that does not extends through said entire magnetic layer;
- and,
- a protective layer that covers said magnetic layer and said groove.
1 more element
A hard disk drive, comprising:
- a base plate;
- a spindle motor coupled to said base plate;
- a disk coupled to said spindle motor, said disk including;
- a substrate;
- a magnetic layer adjacent to the substrate, said magnetic layer having at least one groove with a depth that does not extends through said entire magnetic layer;
- a protective layer that covers said magnetic layer and said groove;
- an actuator arm coupled to said base plate;
- a voice coil motor coupled to said actuator arm;
- and,
- a perpendicular recording head structurally coupled to said actuator arm and magnetically coupled to said disk.
