Abstract
A slider includes a slider body having a trailing edge and a leading edge. The slider also includes a thin film structure deposited in layers on the trailing edge. The thin film structure includes a write transducer configured to read and write to a storage medium. The thin film structure also includes a non-thermally activated actuator at least partially formed with the write transducer and configured to move the write transducer relative to the trailing edge.
Claims23
A slider comprising:
- a slider body having a trailing edge and a leading edge;
- a thin film structure deposited in layers on the trailing edge, the structure comprising:
- a write transducer;
- and
- a non-thermally activated actuator at least partially formed coplanar with the write transducer and configured to move the write transducer relative to the trailing edge, the actuator including a first layer, a second layer and a third layer, wherein the second layer is positioned between the first layer and the third layer and has a stiffness, further wherein the first layer and the third layer have a stiffness that is greater then the stiffness of the second layer.
A method of manufacturing a slider, the method comprising:
- providing a slider body having a trailing edge and a leading edge;
- forming a thin flint structure deposited in layers on the trailing edge comprising;
- forming a write transducer;
- forming a non-thermally activated actuator at least partially coplanar with the write transducer and configured to move the write transducer relative to the wailing edge;
- and
- forming a first layer, a second layer and a third layer, wherein the second layer is positioned between the first layer and the third layer and has a stiffness, further wherein the first and third layer have a stiffness that is greater than the stiffness of the second layer.
A slider comprising:
- a slider body having a trailing edge and a leading edge;
- a thin film structure deposited in layers on the trailing edge, the structure comprising:
- a write transducer configured to write data to a storage medium;
- and
- a non-thermal adtuator means formed at least partially coplanar with the write transducer for moving the write transducer in a direction perpendicular to a bearing surface and relative to the trailing edge.
