Abstract
The present invention is directed to the fabrication of head sliders for use in hard disk drives, and in particular the provision and usage of electrical bond pads on the slider surface structure to accommodate needs of the fabrication process as well as slider operation within a disk drive.
Claims8
A method of processing a slider usable within a disk drive and having magnetic read and write transducers, comprising the steps of:
- performing lapping operation an air bearing surface of at least one slider including magnetic read and write transducers with associated bonding pads along with at least one electrical lapping guide;
- monitoring progress of the lapping operation by measuring electrical resistance of the electronic lapping guide by probing an electrical lapping guide bond pad;
- ceasing the lapping operation at least partially based upon the measurement of a predetermined electrical resistance of the electrical lapping guide;
- and
- after the lapping operation is ceased, electrically connecting the electrical lapping guide bond pad to a transducer device bond pad of the slider by way of a shunt element, which electrical connection allows for electrical signals to and from a transducer device by way of the electrical lapping guide bond pad.
