7, the disk drive unit 109, and the display unit 11
Connected to 1. The ROM 103 stores programs for operating various functions including the disk resume function of the disk player of the present invention, related system data, and the like. The user uses the operation unit 105 to play the disk, adjust the reproduction volume, insert and remove the disk from the disk drive unit 109, and input the user identification information of the present invention.
5 can be performed.

Regarding the input of the user identification information,
Specifically, the method of inputting and registering an individual password for each individual or each group as in the present invention is preferable because of its operability, simplicity, practicality and practicality. There are a plurality of individual buttons, operation keys, switches, etc., and they are switched and input and registered and managed, such as registration and removal with a card, etc.
Various input means using existing technology may be considered.

The nonvolatile RAM 107 is used as a working area, and reads and writes information related to a disk to be reproduced, such as "DNo. (Disk number), TNo. (Track number), time, TOC data, etc." Perform
Here, the TOC information refers to information including the total number of tracks 201 of the disc inserted into the disc drive unit 109 and the total time of all the songs recorded on the disc. Thus, the disc identification information including the plurality of disc identification information / play position information and the user identification information according to the present invention are stored and stored in the nonvolatile RAM 107.

FIG. 2 is a flowchart showing a resume function in the disk reproducing apparatus according to the present invention. The input of the user identification information in FIG. 2 is described using a specific means of registering (backing up) by inputting a personal identification number for each individual or group. Starting from the start (step S11),
If “Yes (Yes)” is determined in “Whether the disc being reproduced has been stopped (Step S13)”, then “Y” is determined. If it is determined to be (Yes), the process proceeds to "Back up DNo./TNo./Time/TOC data for each security code played last (step S14)". In the steps so far, the disc identification information according to the present invention,
Play position information and user identification information (password input in FIG. 2) have been obtained.

[0015] In addition, the message "Did you play with a password?
(Step S12) ", if N (No) is determined,
Then, the message "Did the playing disk be stopped? (Step S15)" is displayed. If Y (Yes) is determined, the "DNo./TNo./Time/TOC data that was played last" is backed up. (Step S16) ". In this step S16, since the personal identification number as the identification information of the user or the like has not been inputted, the information is not stored and stored for each personal identification number by the user group or the like. Therefore, the resume function based on the user identification information (by password) does not work.

Next, it is determined whether "Resume function has been selected after the password is entered (Step S17)". Here, if Y (Yes), it is determined whether the clamped disk is the same as the disk that was backed up (step S18). Playback is started from the place where the backup was made (step S19), and the resume function of the disk playback device is operated, so that replay can be executed from the original position (place) of the previous disk. On the other hand, in the determination of "is the clamped disk the same as the backed-up disk? (Step S18)", if N (No), then "reproduce from the first song of the normally selected DNo. (Step S2)
0) ”.

In addition, "Resume after inserting a password
Is the (Resume) function selected? (Step S17) "
If (No), the process proceeds to “Is the resume function selected (Resume function?) (Step S21)” where Y (Yes)
Then, "is the clamped disk the same as the disk backed up? (Step S22)" is determined, and
Therefore, if Y (Yes), it means "start playback from the place where backup was made (step S23)". In step S23, since the personal identification number as the user identification information has not been input, the information is not stored and stored for each user (for each personal identification number). Therefore, the resume function based on the user identification information (by password) does not work.

On the other hand, if "Resume function is selected? (Step S21)", if N (No), then "Reproduction request? (Step S24)" is determined, and Y ( If (Yes), the message "DNo.
From the first song (Step S25). " If N is "No" in "reproduction requested? (Step S24)", the process returns to "Is the resume function selected after entering the personal identification number? (Step S17)".
Repeat the same steps as above.

Based on the flowchart of FIG. 2, the outline of the disk reproducing apparatus of the present invention is briefly summarized as follows. It is assumed that each of a plurality of family members uses one disk reproducing device. It is necessary for each person to input and register user identification information in the device by PIN registration, etc., and before starting playback, register the user identification information (in this case, the PIN) in the device, Disc playback is performed using a disc playback device. At this time, if disc playback such as movie or music is stopped halfway, DNo.
When the TNo., Time, TOC information of the disk, etc. are backed up on the device and you want to start playback again from that location, enter the password and select the resume function, and the same location as where you last saw or heard Can be played back. If the TOC information of the disc is different, the disc is different, and the reproduction is started from the beginning of the disc. When sharing and using, for example, a mode that can be used without inserting a password may be provided.
