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 in 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 invention provides a magnetic head slider and a manufacturing method of the magnetic head slider. The present invention is to achieve higher-precision recording and / or reproduction of magnetic information by reducing the magnetic spacing between the magnetic head element portion and the magnetic disk. In an embodiment of the present invention, the pitch is adjusted by thermal expansion of the head element portion caused by heat from the heater element 15 on the slider. Furthermore, in the magnetic head structure of the present embodiment, grooves are provided in the return pole 131 of the recording head 13 and / or the shield 113 of the reproducing head 11 . In addition, grooves are formed in the coating along with the grooves described above. The grooves reduce the effect of return pole or shield protrusion on magnetic spacing control.

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 ...
