A METHOD FOR CONTROLLING OVERCOAT RECESSION IN A MAGNETIC THIN FILM HEAD |
摘要 |
The overcoat of a slider (alumina) is recessed relative to the slider ABS by a non-abrasive CMP process sufficiently to prevent thermal protrusion of the overcoat during subsequent slider use in a hard disk drive. The CMP process involves the oscillatory and rotational compressional contact between the ABS surface of the slider and a polymerically pre-treated compliant pad that is sprayed by an aqueous alkali lubricating solution having a pH between about 9 and 10. The overcoat is thereby also softened by the lubricating solution and removed by the compressional contact and no use of abrasives is required. |
