Problems solved by technology

Therefore, these methods have the problem that these methods are not suitable for mass production of products (for example, magnetic disks) that require precise processing over such a wide area as such
Such tight control is possible if the area for arranging the nanoparticles is narrow, but it is almost impossible to perform such strict control if the nanoparticles are arranged in a wide area (for example, over the entire surface of the magnetic disk 11), so now It is almost unrealistic to mass-produce the magnetic disk 11 using the nanoparticle alignment method based on the flow-mediated aggregation method

Embodiment Construction

[0089] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0090] FIG. 4 is a flowchart showing a magnetic disk manufacturing method as one embodiment of the present invention.

[0091] The magnetic disk manufacturing method shown in FIG. 4 corresponds to one embodiment of the magnetic disk manufacturing method according to the present invention, and the method is formed by forming a multi- A method for manufacturing a magnetic disk with a 1-bit region 11a, the method includes a stamper preparation step (step S100) and a manufacturing step (step S200).

[0092] As explained with reference to FIG. 1, each 1-bit area 11a is obtained by filling minute holes piercing the disk with a magnetic material. The stamper preparation step (step S100) is a step of producing an imprint mold (stamper) for embossing a concave portion (cavity) on an aluminum substrate in a subsequent manufacturing step (step S200), which The recesses are forme...

Abstract

The invention provides a nanostructure manufacturing method, a magnetic disk manufacturing method, a stamper forming method and a matrix generating method. The nanostructure manufacturing method comprises the steps of: forming a particle layer on the substrate by spreading at least one layer of nanoscale particles made of a material different from that of the nanoscale flat substrate; forming a holding layer on the particle layer. a body that holds the particle layer by being closely bonded to particles forming the particle layer; and removing the substrate in such a manner that the particle layer remains intact.

Description

technical field [0001] The present invention relates to a nanostructure manufacturing method for producing a nanoscale concave-convex structure (nanostructure), a magnetic disk manufacturing method for producing a magnetic disk using such a nanostructure, a method of forming a stamper as an imprint mold having a nanostructure, and a nanostructure A matrix generation method in which structures are formed on a predetermined base material. Background technique [0002] In the field of computers, a large amount of data is routinely handled, and a hard disk drive (HDD) is used as a device for recording and reproducing such a large amount of data. Such an HDD includes a magnetic disk in the shape of a disk as a magnetic recording medium for recording data, and a magnetic head for recording data on and reproducing data from the magnetic disk. [0003] Generally, a magnetic disk made of a uniform magnetic material is known which is approaching its limit in terms of data recording d...
