Abstract:
1. A system for fabricating sliders for magnetic recording comprising: lapping hardware for lapping an air-bearing surface of a slider; means for electrically connecting to lead pads on the slider, a first measurement unit, connected to two leads pads that are connected to a read sensor or an electro-lapping guide for the read sensor, which measures a first electrical resistance and generates a first digital signal encoding the first electrical resistance; a second measurement unit, connected to two leads pads that are connected to an electro-lapping guide aligned with a selected structure in a write head in the slider, which measures a second electrical resistance and generates a second digital signal encoding the second electrical resistance; and a controller that stops the lapping hardware when target conditions for the stripe height are met using the first digital signal as a measure of a current stripe height and target conditions for the selected structure in the write head are met using the second digital signal as a measure of a current lapping plane's proximity to a target air-bearing surface for the write head.
