Method of operating a disk drive including rotating a perpendicular write head to reduce a difference between skew and taper angles, and a disk drive
View Patent ↗A method of operating a disk drive including providing the disk drive. The disk drive includes a disk with data tracks and an actuator with a slider including a perpendicular magnetic write head. The write head includes leading and trailing sides defining a taper angle. The write head and the actuator define a maximum skew angle with respect to the data tracks. The maximum skew angle being greater than the taper angle. The method further includes rotating the slider during operation of the disk drive to reduce a difference between the skew and taper angles for aligning the write head with the data tracks.
1. A method of operating a disk drive, the method comprising:
a) providing the disk drive including a disk with data tracks and an actuator with a slider including a perpendicular magnetic write head, the write head including leading and trailing sides defining a taper angle, the write head and the actuator defining a maximum skew angle with respect to the data tracks, the maximum skew angle being greater than the taper angle, and
b) rotating the slider during operation of the disk drive to reduce a difference between the skew and taper angles for aligning the write head with the data tracks.
2. The method of claim 1 wherein the taper angle is between 5 to 10 degrees and the maximum skew angle is between 15 to 18 degrees.
3. The method of claim 1 wherein the slider is able to be rotated at least 30 degrees.
4. The method of claim 1 wherein the taper angle is between 5 to 10 degrees and the maximum skew angle is between 11 to 13 degrees.
5. The method of claim 1 wherein the slider is able to be rotated at least 15 degrees.
6. The method of claim 1 wherein the actuator includes an actuator body and the slider is rotated relative to the actuator body.
7. The method of claim 1 wherein the write head includes a write pole, an opposing return pole and an electrically conductive magnetizing coil disposed about the write pole, the leading side of the write head is disposed upon the write pole between the write pole and return pole, the trailing side of the write head is disposed upon the write pole opposite the leading side.
8. A disk drive comprising:
a disk drive base;
a disk rotatably coupled to the disk drive base, the disk includes data tracks; and
an actuator rotatably coupled to the disk drive base, the actuator including a slider including a perpendicular magnetic write head, the write head including leading and trailing sides defining a taper angle, the write head and the actuator defining a maximum skew angle with respect to the data tracks, the maximum skew angle being greater than the taper angle, the slider being rotatable with respect to the data tracks to reduce a difference between the skew and taper angles for aligning the write head with the data tracks.
9. The disk drive of claim 8 wherein the taper angle is between 5 to 10 degrees and the maximum skew angle is between 15 to 18 degrees.
10. The disk drive of claim 8 wherein the slider is able to be rotated at least 30 degrees.
11. The disk drive of claim 8 wherein the taper angle is between 5 to 10 degrees and the maximum skew angle is between 11 to 13 degrees.
12. The disk drive of claim 8 wherein the slider is able to be rotated at least 15 degrees.
13. The disk drive of claim 8 wherein the actuator includes an actuator body and the slider is rotatable relative to the actuator body.
14. The disk drive of claim 8 wherein the write head includes a write pole, an opposing return pole, and an electrically conductive magnetizing coil disposed about the write pole, the leading side of the write head is disposed upon the write pole between the write pole and return pole, the trailing side of the write head is disposed upon the write pole opposite the leading side.
