Embodiment Construction

[0058] Hereinafter, preferred embodiments to which the present invention is applied will be described. For clarity of explanation, the following description and drawings may include appropriate omissions and simplifications. In all the drawings, the same components are denoted by the same reference numerals, and repeated descriptions will be omitted for clarity of explanation if not necessary. Hereinafter, an embodiment of the present invention will be described in which a hard disk drive (HDD) is used as an example of a magnetic disk drive.

[0059] The present embodiment is characterized by the structure of the head element portion in the head slider to be mounted on the HDD. The recording head of the magnetic head slider of this embodiment is a perpendicular recording head. A perpendicular recording head includes a main pole for generating magnetic flux that changes the magnetization of a recording layer of a magnetic disk, and a return pole for returning to the return po...

Abstract

The present invention provides a head-slider and a manufacturing method thereof. According to the invention, recording and / or reproducing of the magnetic information with higher precision are realized through reducing the magnetic clearance between a magnetic head component and a magnetic disc. In an embodiment of the invention, the clearance is regulated through the thermal expansion of the magnetic head component, which is caused by the heat from a heater component 15 on the slider. Besides, in the magnetic head component of the embodiment, a groove is equipped in a return electrode 131 of a record head 13 and / or a shield 113 of a reproducing head 11. Furthermore, the groove is formed in a coating along with the groove mentioned above. The groove can reduce the effect by the protrusion of the returning electrode or shielding to the control of magnetic clearance.

Description

technical field [0001] The present invention relates to a kind of magnetic head slider (magnetic head slider) and the manufacturing method of magnetic head slider, particularly, the present invention relates to a kind of magnetic head slider with heater element, and this heater element is used for adjusting magnetic head The spacing between the component part and the disk. Background technique [0002] Disk drive devices using various disks, such as optical disks, magneto-optical disks, and flexible disks, are well known in the art. In particular, hard disk drives (HDDs) have been widely used as storage devices for computers, and have become one of the storage devices necessary for current computer systems. In addition, HDDs are widely used in video recording / reproducing devices, car navigation systems, mobile phones, and the like in addition to computers due to their remarkable characteristics. [0003] An HDD consists of a magnetic disk and a slider; data on the disk is ...
