Tape head with thin support surface and method of manufacture
View Patent ↗According to one aspect, an exemplary method of manufacturing a magnetic head assembly with a predetermined wrap angle is described. The method includes removing a portion of a magnetic head support surface to create a slot transverse to a direction the media advances and at least partially separating a major support surface having an active device region and a thin support surface. The method further includes removing a portion of the thin support surface such that the height of at least a portion of the thin support surface is reduced relative to the major support surface. The height may be reduced to achieve a predetermined wrap angle between the media and the major support surface of the head assembly.
1. A method for manufacturing a magnetic head for use with magnetic storage media, comprising:
removing a portion of a magnetic head support surface to create a slot transverse to a direction the media advances and at least partially separating a major support surface having an active device region and a thin support surface; and
removing a portion of the thin support surface such that the height of at least a portion of the thin support surface is reduced relative to the major support surface.
2. The method of claim 1 , further including removing a portion of the magnetic head support surface to create a slot parallel to the direction the media advances.
3. The method of claim 1 , wherein the portion of the thin support surface is removed to create a desired wrap angle between the media and the major support surface.
4. The method of claim 1 , wherein removing the portion of the thin support surface includes removal with a lapping tape.
5. The method of claim 1 , wherein removing the portion of the thin support surface includes removal with use of the media.
6. The method of claim 1 , wherein removing a portion of a magnetic head support surface includes machining.
7. The method of claim 1 , wherein removing a portion of a magnetic head support surface includes laser ablation.
8. The method of claim 1 , wherein the width of the slot is between approximately 3 to 5, milli-inches.
9. The method of claim 1 , wherein the width of the thin support surface is between approximately 2 to 3 milli-inches.
10. The method of claim 1 , wherein a ratio between the width of the slot measured along the direction the media advances and the thin support surface is between approximately 1 and 3.
11. The method of claim 1 , wherein the thin support surface forms a perimeter around the major surface.
12. The method of claim 1 , wherein the slot extends in a perimeter around the major surface.
