本発明は光ディスク、カード状光記録媒体等の板状記録
媒体に係り、特に性能検査の能率向上を図りうる板状記
録媒体に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a plate-shaped recording medium such as an optical disk or a card-shaped optical recording medium, and particularly to a plate-shaped recording medium that can improve the efficiency of performance inspection.

所定の数に等分割することＫより形成されている。Conventional plate-shaped recording media, such as optical discs, have a guide groove called a pre-group that constitutes an information recording area, and a number data formed in a part of the pre-group, that is, a ring for classifying the information to be recorded. It has number data indicating a sector number indicating a sector address. Incidentally, the sector address is formed by equally dividing one track into a predetermined number of parts, such as 32 parts, 64 parts, etc., for example.

る。By the way, in the manufacturing process of optical discs, performance inspections are generally conducted to check for defects such as dropouts that may cause errors in recording information before making them into finished products. In such cases, it is necessary to clearly indicate the location in order to eliminate the defect. Normally, such performance inspections of optical disks involve loading the optical disk into a disk drive, driving the disk drive, reading out the sector number provided on the optical disk to check for defective locations, and examining the surface of the optical disk using, for example, a microscope. We carry out a so-called visual inspection in which we visually confirm the defects using a disc drive, etc., and if there is a defect, we add a mark to the optical disc to clearly indicate its location. I am asking you to correct the defects.

具合がｔ・つた。However, although the number data indicating the sector number on an optical disk is visible as a linear shape with a certain width, it is not possible to visually determine which sector number the linear shape specifically indicates. In other words, it is not possible to visually confirm which sector address the mark added to the optical disk is included in. Therefore, after adding the mark, the disk is manufactured into a disk drive and the mark is removed. The troublesome work of checking the added sector address by detecting the sector number is required, and therefore there is a problem in that the efficiency of the presexual examination cannot be expected to be improved.
