Abstract
A head slider with a precise positioning actuator includes a thin plane shaped head section provided with a first surface that is substantially perpendicular to an ABS of the head slider, a second surface opposite to the first surface and at least one head element formed on the first surface, and an actuator section located at a side of the second surface of the head section and integrally fixed to the head section, for precisely positioning the at least one head element.
Claims30
A head slider with a precise positioning actuator, comprising:
- a thin plane shaped head section provided with a first surface that is substantially perpendicular to an air bearing surface of said head slider, a second surface opposite to said first surface and at least one head element formed on said first surface;
- and
- an actuator section located at a side of said second surface of said head section and integrally fixed to said head section, for precisely positioning said at least one head element.
A manufacturing method of a head slider with a precise positioning actuator, comprising the steps of:
- forming a plurality of head elements on a front surface of a head element substrate;
- grinding a rear surface of said head element substrate with said plurality of head elements formed to have a thin head element substrate;
- dicing said thin head element substrate into a plurality of individual first members;
- and
- integrally fixing a second member with at least one precise positioning actuator section to each of said first members so as to obtain a fixed member with said at least one precise positioning actuator section located at a rear surface side of said first member.
