Abstract

A head slider includes a slider that is disposed at a tip of a supporting member, floats with an air flow occurring due to rotation of a storage medium, and has a medium facing surface onto which a water-repellent material is applied, with an area near the magnetic head being exposed; and a magnetic head that is disposed at an air outflow end side of the slider and has a recording element and a reproducing element.

Claims (28)

1 . A head slider comprising:

a slider that is disposed at a tip of a supporting member, floats with an air flow occurring due to rotation of a storage medium, and has a medium facing surface onto which a water-repellent material is applied, with an area near the magnetic head being exposed; and

a magnetic head that is disposed at an air outflow end side of the slider and has a recording element and a reproducing element.

2 . The head slider according to claim 1 , wherein

a distance from a position on an air inflow end side near the magnetic head to an air outflow end side of the slider is represented by a value obtained by dividing a film thickness of the water-repellent material by a tangent of a pitch angle when the slider floats.

3 . The head slider according to claim 1 , wherein

the water-repellant material is water-repellant resin.

4 . The head slider according to claim 1 , wherein

the water-repellant material is a chemical absorption layer formed by a chemical reaction between the water-repellant resin and the medium facing surface of the slider.

5 . A magnetic storage device comprising:

a storage medium;

a slider that is disposed at a tip of a supporting member, floats with an air flow occurring due to rotation of a storage medium, and has a medium facing surface onto which a water-repellent material is applied, with an area near the magnetic head being exposed;

a magnetic head that is disposed at an air outflow end side of the slider and has a recording element and a reproducing element; and

a signal processing board that processes a reproducing signal and a recording signal for reproducing and recording information by the storage medium and the magnetic head.

6 . A head-slider manufacturing method of manufacturing a head slider with a magnetic head having a recording element and a reproducing element to cause the magnetic head to float over a storage medium, the method comprising:

forming a lubricating layer on a medium facing surface of the head slider;

irradiating the lubricating layer formed in the forming with a high energy beam except a portion near the magnetic head;

cleaning the lubricating layer irradiated with the high energy beam in the irradiating by using a solvent that can solve a lubricating agent that forms the lubricating layer.

7 . The head-slider manufacturing method according to claim 6 , further comprising:

forming a resist on a portion near the magnetic head of a medium facing surface of the lubricating layer prior to the irradiating, and

removing the resist after the irradiating.

8 . The head-slider manufacturing method according to claim 6 , wherein

in the irradiating, only a portion of the lubricating layer formed in the forming except the portion near the magnetic head is irradiated with the high energy beam.

9 . A head-slider manufacturing method of manufacturing a head slider with a magnetic head having a recording element and a reproducing element to cause the magnetic head to float over a storage medium, the method comprising:

forming a resist near the magnetic head on a medium facing surface of the head slider;

forming a lubricating layer on the medium facing surface having the resist formed thereon in the forming;

irradiating the lubricating layer formed in the forming with a high energy beam; and

cleaning the lubricating layer irradiated with the high energy beam in the irradiating by using a lubricant-soluble solvent.
