内径部及び外径部を刃物で切削していた。The process of applying photoresist to the glass disk, the process of forming an information surface on the photoresist layer by laser cutting,
Sputtering or AI on the information surface! When separating the disk master, which is formed through the process of forming a metal film by vapor deposition and the process of applying nickel plating on the metal film, from the glass disk, the disk master is rotated, and the inner diameter and The outer diameter part was cut with a knife.

の製造方法を提供するものである。Conventional methods not only scratch the glass disk, but also make cutting difficult because the degree of adhesion between the glass disk and the nickel plating varies depending on the position, and causes warping and cracking at the edges of the master disk after cutting. - [Objective] An object of the present invention is to provide a method for manufacturing a disk master that does not cause warping or cracking in the master when separating the glass disk and the disk master.

る。The production of a disk master according to the present invention includes (1) a closing member (3) that closes a hole (2) that is connected to a center hole (2) of a glass disk (1); Insert it so that it is flush with the surface (see Figure 1 (a)). (1
1) Apply photoresist on certain glass disks (1) and closure members (3). (liDthis photoresist layer (
4) Form the information surface by laser cutting. (1
v) On this photoresist layer (4), a metal film (5J?) is formed by sputtering or 11 layers (see Figure 1 (b)).M On this metal film (5), nickel plating (61&
Apply (see Figure 1 (1 ml). (vl) Glass disk (
1) Pull out the closing member (3) from the center hole (2), and use the center hole (2) as a guide to punch the center hole of the disk master using the punch (7) (see Figure 2). After the viD disk master is separated into glass disks (1), the outer shape is cut around the center hole of the master to form a disk master.

加工出来る。Since the center hole of the disk master is formed using the center hole of the glass disk as a guide, it is possible to form the center hole of the master with high accuracy, and there is no warping or cracking of the master. Since the outer shape is cut around the hole, the outer dimensions of the disk master can be processed with high precision.
