Embodiment Construction
[0035] An embodiment in which the disk device according to the present invention is applied to a hard disk drive (HDD) will now be described in detail with reference to the drawings.
[0036] As shown in FIG. 1, the HDD has a housing 12 in the form of a rectangular box with an open top and a top cover (not shown). The top cover is fastened to the case body by screws so as to close the top opening of the case body.
[0037]The case 12 includes a magnetic disk 16, a spindle motor 18, a magnetic head 40, a carriage assembly 22, a voice coil motor (VCM) 24, a ramp load mechanism 25, a board unit 21, and the like. The magnetic disk 16 is used as a recording medium. The spindle motor 18 serves as a driving section for supporting and rotating the magnetic disk. The magnetic head writes and reads information on the disk. The carriage assembly 22 supports the magnetic head for movement relative to the magnetic disk 16 . VCM 24 rocks and positions the carriage assembly. When the he...

Abstract
According to one embodiment, a slider of a head has a negative-pressure cavity formed in a facing surface, a leading step portion which protrudes from the facing surface and is situated on an upstream side of the negative-pressure cavity with respect to an airflow, a trailing step portion which protrudes from the facing surface and is situated on a downstream side of the negative-pressure cavity with respect to the airflow, and a trailing pad which protrudes from the trailing step portion. The trailing pad has a base portion provided on the trailing step portion and situated on the outflow end side of the slider, a pair of wing portions extending from the base portion to opposite sides in a second direction, and two extending portions which individually extend from the base portion to the upstream side of the airflow and define a recess which opens toward the negative-pressure cavity.
Description
technical field [0001] The present invention relates to a head used in a disk device such as a magnetic disk device, a head suspension assembly provided with the head suspension assembly, and a disk device including the head suspension assembly. Background technique [0002] A disk device such as a magnetic disk device includes a magnetic disk, a spindle motor, a magnetic head, and a carriage assembly. A magnetic disk is arranged in the case, and a spindle motor supports and rotates the disk. The magnetic head writes and reads information on the platter. A carriage assembly supports the head for movement relative to the disk. The carriage assembly includes a rockable support arm and a suspension extending from the arm. The magnetic head is supported on the extended end of the suspension. The head has a slider attached to the suspension and a head portion on the slider. The head portion is configured to include a reproducing element for reading and a recording element fo...
