Title: Magnetic disk, magnetic disk device and formation of substrate for magnetic disk
Inventor: MORITA OSAMI
IPC: G11B5/84
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To simplify manufacturing processes and to reduce the cost by forming an area to be in contact with a head slider into a pattern of projecting put arrays and also making a floating amt. reference plane of this contact area higher than that of an information area. SOLUTION: The substrate for the magnetic disk 3 can be produced by injection molding using a stamper applied to an optical disk, etc., and in the case of a flat type magnetic disk, a CSS zone 3a can be formed with the pit arrays at the same time that the shape of the substrate for the magnetic disk is formed. Then, in the case of a discrete type magnetic disk, a CSS zone 3a can be formed with the pit arrays at the same time that the shape of the substrate of the magnetic disk is formed, while projecting and recessed parts of a data zone 3b can also be formed. Consequently, the magnetic disk 3 having the CSS zone 3a can be produced in the same number of processes as a magnetic disk without a CSS zone 3a.

Title: Code card system
Inventor: ISHIKAWA YASUO
IPC: G06K19/06
Filed: 1994-12-22
Abstract: PURPOSE: To securely detect an illegal card by writing use state code in a use state confirmation area each time the card is used, confirming the use state code, and comparing it with the contents of a balance code area and judging whether or not the card is illegally used. CONSTITUTION: Data 2 for state confirmation are read out and the matching judgement process of the card is performed. This process is performed by confirming data 2 for state confirmation stored in the use state confirmation area 3 with the contents of a balance code area written on the card 1 by reading write information by a read head. When the frequency of use indicates 0, the state confirmation data 2 is 0 and nothing is written in the corresponding balance code area. When it is judged from the collation result that the state confirmation code 2 and the information in the balance code area match each other, the card is judged to be normal and the balance is rewritten. When not, on the other hand, the card is judged to be an illegal and the read process is quit.
