Embodiment Construction
[0043]The invention proposes a new contact hard disk magnetic head, which includes a magnetic head slider and a pole tip. The size of the magnetic head slider is designed to be micron through the wafer processing process. The bottom surface of the magnetic head slider has a side length of 50-800 μm and a height of 30 -200 μm. There is no need to perform complex air bearing surface design on the lower surface of the magnetic head slider, but it is only necessary to polish the bottom surface of the magnetic head slider using known polishing techniques to obtain a flat surface.
[0044] The structure of the magnetic head of the contact hard disk of the present invention and its manufacturing method will be described in detail below with reference to the accompanying drawings.
[0045] According to the first embodiment of the present invention, such as figure 1 As shown, a magnetic head of a contact hard disk is provided, including a magnetic head slider 1, a pole tip 2, a super ...

Abstract
The invention provides a magnetic head structure and a preparation method of a contact hard disk which simplifies the process and is easier to realize and mass-produce. Specifically, the magnetic head of the contact hard disk includes a magnetic head slider and a pole tip, and is characterized in that: the magnetic head slider includes a surface and a bottom surface; a plurality of super slides are arranged on the bottom surface of the magnetic head slider; each of the super The upper surface of the slider is connected to the bottom surface of the magnetic head slider through a connection structure; the height of the lower surface of the super slider from the surface of the magnetic head slider can be adjusted.
Description
technical field [0001] The invention relates to a large-capacity storage device, in particular to a contact hard disk magnetic head based on the super-slip structure technology. Background technique [0002] With the increasing storage capacity of the hard disk, the particles of the disk storage medium are decreasing day by day. In order to ensure the reliability of data access, the flying height of the magnetic head is also decreasing. In order to obtain sufficient resolution, the volume and weight of the magnetic head slider are required. Getting smaller and smaller. [0003] At present, the reading and writing of hard disks are performed by suspending the magnetic head at a height of several nanometers above the disk body. Magnetic storage technology is a near-field technology. When reading and writing magnetic information, the magnetic field strength increases with the distance between the magnetic head and the magnetic medium. Exponential decay. At present, the size o...
