Abstract
There are provided: an optical pickup feed mechanism (12) that detects a disk signal; a disk loading mechanism (11) that feeds a disk D by means of a loading roller (11b) that is driven by a loading motor (11a); a mechanism control section (20) that controls drive of the loading motor (11a); and an authentication control section (30) that authenticates the authorized user and outputs a disk ejection instruction to the mechanism control section (20) if the registered password and disk ejection instruction are input.
Claims22
A disk drive device comprising a signal detection section that detects a disk signal and a disk ejection mechanism that ejects a disk, characterized in that said disk drive device comprises:
- mechanism control means that controls the drive of said disk ejection mechanism and authentication control means that outputs a disk ejection instruction to said mechanism control means when a disk ejection instruction and authentication information are input,
- said authentication control means being connected with authentication information input means that inputs authentication information, and
- said authentication control means comprises:
- an authentication information storage section that stores prescribed authentication information;
- a decision section that determines whether or not the authentication information that is input from said authentication information input means agrees with the authentication information that is stored in said authentication information storage section;
- and
- a disk ejection instruction section that outputs a disk ejection instruction to said mechanism control means if a disk ejection instruction is input and said decision section determines that the authentication information is in agreement,
- said authentication information includes disk-specific information that is detected by said signal detection section on the disk and stored in said authentication information storage section, said disk-specific information is selected from one or more of the disk title, file name, holder name, table of contents information and playing time;
- and
- a display screen for displaying disk-specific information when a disk is inserted into the disk drive device and a user is enabled to select from the disk-specific information the authentication information to be stored by the authentication information input means.

A disk drive device comprising a signal detection section that detects a disk signal and a disk ejection mechanism that ejects a disk, characterized in that said disk drive device comprises:
- a loading roller in the disk ejection mechanism for contacting the disk to insert and remove the disk to and from the disk drive device;
- a display screen displaying disk-specific information when the disk is inserted into the disk drive device;
- an operator input section that enables an authentication control section to designate and enter authentication information selected by the operator from the disk-specific information unique to the disk displayed on the display screen;
- a registration management section that manages the authentication information and stores the selected portion of the disk-specific information designated by the operator from the display screen as the authentication information in a memory when a password entry mode of operation is enabled;
- mechanism control section that controls the drive of said disk ejection mechanism;
- an authentication control section that outputs a disk ejection instruction to said mechanism control means when a disk ejection instruction and authentication information are input, said authentication control section being connected with the operator input section that inputs authentication information, and comprises:
- a decision section that determines whether or not the authentication information that is input from said operator input section agrees with the authentication information that was stored in said memory during the password entry mode of operation;
- and
- a disk ejection instruction section that outputs a disk ejection instruction to said mechanism control section if a disk ejection instruction is input and said decision section determines that the inputted authentication information is in agreement with the stored authentication information in the memory.
