Embodiment Construction

[0021] The embodiments of the present invention generally provide an apparatus and method for processing a magnetic medium substrate, which may be used as a storage medium in a hard disk drive, for example. The device and method change the magnetic properties of the substrate by applying energy to the substrate in a patterned manner to generate magnetic domains with different properties, and the properties of the magnetic domains can be detected and changed by the magnetic head. These magnetic domains can be individually addressed by a magnetic head, which is held near the surface of the substrate so that the magnetic head can detect and affect the magnetism of a single magnetic domain. The size of the magnetic domain generated by the embodiment of the present invention is less than about 25 nm, while maintaining the topography of the substrate.

[0022] The substrate used is usually metal or glass, but can also be a metal alloy or composite glass material, such as a glass / cerami...

Abstract

Methods and apparatus for forming substrates having magnetically patterned surfaces are provided. A magnetic layer comprising one or more magnetic materials is formed on the substrate. The magnetic layer is patterned, and a plurality of parts of the surface of the magnetic layer are selected to be changed during the process, and the changed part has a magnetic property different from that of the unaltered part without changing the morphology of the substrate. A protective layer and a lubricating layer are deposited on the patterned magnetic layer. Patterning is accomplished by exposing the substrate to different forms of energy through a number of alternative processes.

Description

Technical field [0001] The embodiments of the present invention relate to a hard disk drive medium and an apparatus and method for preparing the hard disk drive medium. More specifically, the embodiments of the present invention relate to a method and apparatus for forming a patterned magnetic medium of a hard disk drive. Background technique [0002] Magnetic layers and magnetic sensitive layers have many applications in the electronics industry. In a prominent example, a hard drive is a special storage medium for computers and related equipment. Hard drives are found in most desktop and portable computers, and can be found in many consumer electronic devices, such as media recorders and players, and instruments used to collect and record data. Hard disk drives can also be deployed in the form of arrays for network storage. [0003] Hard drives store information magnetically. The disk in a hard disk drive is provided with magnetic domains that can be individually addressed by ...
