摘要： PROBLEM TO BE SOLVED: To provide a memory device which very accurately detects contact between a head slider and a storage medium, and to provide a method for determining the contact of a head slider. SOLUTION: A protrusion 48 contacts a storage medium 14 on the basis of increased electric signals. The protrusion 48 moves up and down by the action of an AC component superposed on the electric signals. Consequently, the contact and non-contact between the protrusion 48 and the storage medium are repeated. When the contact occurs, frictional force is generated between the protrusion 48 and the storage medium 14. The head slider 22 is dragged along the surface of the storage medium 14. Alternatively, when the contact does not occur, the frictional force is not generated. The head slider 22 is dragged to return to the initial position. Thus, the head slider 22 oscillates, and a head suspension 21 also oscillates at the same time. The frequency of the AC component accords with the natural frequency of the head suspension 21, and consequently the head suspension 21 resonates. On the basis of the resonance, the contact to the storage medium 14 is very accurately detected. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a head slider and a storage device with which adhesion of a lubricant to the slider body is suppressed.
SOLUTION: The distance between bottom faces of grooves 42a, 42b and the storage medium is increased at a front rail 33. As a result, collision of lubricant molecules and air molecules takes place many times, and the air molecules eject the lubricant molecules. Still more, air accumulated in the grooves 42a, 42b flows to the air-bearing surface 36 closer to the air flow out side than the grooves 42a, 42b and the air pressure at the air-bearing surface 36 is increased. As a result, the number of air molecules is increased between the air bearing surface 36 and the storage medium; and consequently, the collision between the lubricant molecules and the air molecules is increased. In addition, the area of the air-bearing surface 36 is reduced due to the formation of the grooves 42a, 42b. Adhesion of the lubricant molecules to the head slider 22 is suppressed. Furthermore, excelling balance of buoyant forces is realized due to a pair of grooves placed with a space between them in the slider width direction, and the head slider 22 stably floats in the air.

摘要： PROBLEM TO BE SOLVED: To provide a head slider of a magnetic disk device in which unstable floating caused by a lubricant drop is made less likely to occur by making the lubricant attached on the slider evaporate more easily.
SOLUTION: Inside a nonmagnetic insulating layer 404 formed in an air outflow end of the head slider, in addition to a heat generating element 410 and a head element 408, a multiple layer heat conducting mechanism 412 which is laminated in a slider longitudinal direction and where at least one layer out of the layers extends to near both the ends of a slider width direction, is embedded. Heat generated by the heat generating element 410 spreads over the nonmagnetic insulating layer 404 efficiently, and the temperature of the whole nonmagnetic insulating layer 404 increases. Therefore, the temperature of the lubricant attached to any place of the nonmagnetic insulating layer 404 increases efficiently, and the lubricant evaporates or flows.
