Abstract
A carrier for a slider row bar for a lapping process. The carrier has a mounting structure comprising a material configured to have a first modulus of at least 1,000,000 Pa at a first period of time and a second modulus of 500 Pa to 500,000 Pa at a second period of time subsequent to the first period. The change from the first modulus to the second modulus is due to an external stimulus on the material.

A carrier for a slider row bar for a lapping process, the carrier comprising a mounting structure comprising a material configured to have a first modulus of at least 1,000,000 Pa at a first period of time and a second modulus of 500 Pa to 500,000 Pa at a second period of time subsequent to the first period, wherein the change from the first modulus to the second modulus is due to an external stimulus on the material.
A carrier for a slider row bar for a lapping process, the carrier comprising:
- a rigid base;
- and
- a mounting structure for attachment of the slider row bar thereto, the mounting structure comprising a plurality of layers, with one of the layers configured to have a shear modulus of at least 1,000,000 Pa at a first period of time and a shear modulus of no more than 500,000 Pa at a second period of time subsequent to the first period, wherein the change in modulus is due to an external stimulus on the material.
A method of lapping a slider row bar, comprising:
- mounting a slider row bar onto a carrier, a portion of the carrier having a first shear modulus;
- rough lapping the slider row bar while mounted on the carrier;
- applying a stimulus to the carrier to change the first shear modulus to a second shear modulus;
- and
- after applying the stimulus, kiss lapping the slider row bar while mounted on the carrier.
