[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a management method for a read-only optical recording medium in the case where the read operation is continued after the read operation of the recorded content from the read-only optical recording medium is interrupted.

[0002]

2. Description of the Related Art FIG. 10 shows an optical recording medium reproducing apparatus A (a reproducing apparatus in the following description) to which a management method of a conventional reproduction-only optical recording medium (abbreviated as an optical recording medium in the following description) is applied. Abbreviated as A). The reproducing apparatus A includes an optical information reproducing head 2, an optical information processing section 3, and a control section 4.
Reference numeral 1 is a CD-ROM which is one type of optical recording medium, and a bit string representing information recorded on the optical information recording surface OR of the CD-ROM 1 reflects the laser beam from the optical information reproducing head 2 and reads it. Be issued. The optical information reproducing head 2 converts the read laser light code into an electric signal code and outputs it to the optical information processing unit 3. The optical information processing unit 3 converts this electric signal into a binary signal and outputs it to the control unit 4.
The control unit 4 obtains the contents of the CD-ROM 1 from this binary signal and performs the requested processing. For example, CD-ROM
The contents of the predetermined portion 1 are output to a printer (not shown).
If the reading operation from the CD-ROM 1 is interrupted, even if the status, which is the data indicating the state of the CD-ROM 1 including the data indicating the interruption point, is obtained, the CD-ROM 1 is a read-only recording medium. This status is lost because you cannot write to.
Therefore, when the read operation of the remaining part is necessary, C
It is necessary to read the D-ROM 1 from the beginning.

When the reading operation of the CD-ROM 1 is interrupted, in order to perform the reading operation of the remaining portion as described above, it is necessary to read the portion before the interruption in duplicate.
ineffective. Therefore, as a method of omitting the work of reading the duplicated portion, a data storage means is provided in the control unit 4 and the CD-ROM
A method of storing the status 1 is used.

FIG. 11 is a block diagram showing the inside of the control unit 4 having the above-mentioned status storage means. As shown in the figure, the control unit 4 includes a control calculation means 41, a program storage means 42, a data storage means 43, an input device 44, a display device 45,
The input / output unit 46 is provided, and the control calculation unit 41 executes the program stored in the program storage unit 42 to execute the control unit 4
Alternatively, the function of the reproducing apparatus A is realized. In the following description, the function realized by executing the program by the control calculation means 41 will be described as the function realized by the program. The data storage means 43 is a storage means for storing data to be referred to when the control calculation means 41 executes the program, data generated by the control calculation means 41, and the like. Area SI is set.
The control unit 4 receives a signal from the optical information processing unit 3 via the input / output unit 46 and outputs a control signal to the optical information processing unit 3. In the program storage means 42, an operation signal input to the input device 44 is input, predetermined data is displayed on the display device 45, a program for controlling the input / output unit 46, and the like of the playback device A and the control unit 4. The basic program P0 which is a program for realizing the basic functions and the reading work of the CD-ROM 1 are monitored, and when the reading work of the CD-ROM 1 is interrupted, the status of the CD-ROM 1 at the time of interruption is created, Status recording program P1 that is a program that stores the created status in the status area SI
Is stored. If the reading operation of the CD-ROM 1 is interrupted, the control unit 4 controls the CD-ROM at the time of interruption.
Create status 1 and store it in status area SI,
When the CD-ROM 1 read operation is restarted, the contents of the status area SI are referred to and C is continued at the previously interrupted location.
The work of reading the contents of the D-ROM 1 is restarted.

[0005]

As described above, in the conventional reproducing apparatus, the reading operation of the optical recording medium is interrupted,
If it is necessary to read the remaining part after the interruption, a method of rereading the optical recording medium from the beginning, and the control unit of the playback device stores the status of the optical recording medium at the time of interruption during the reading operation. When the reading operation from the optical recording medium is interrupted, the status of the optical recording medium including the data indicating the interrupted portion of the optical recording medium is stored in the data storage means of the control unit of the reproducing device. Incidentally, when resuming the reading operation of the optical recording medium, referring to the status of the optical recording medium stored in the data storage means of the control unit, the reading operation of the optical recording medium is started from the position following the interrupted position. There was a way to do. In the case of the former method, there was a waste of duplicating the parts before the interruption. In the latter method, when the read operation of one optical recording medium is interrupted, the read operation of the other optical recording medium is interrupted, and the read operation of this optical recording medium is interrupted, the first operation There is a drawback that the status of the optical recording medium is lost. Even if the control unit has a function that can store multiple statuses,
The troublesomeness of status management is caused by storing a plurality of statuses.

In view of the above circumstances, the present invention provides
When the reading operation of the optical recording medium is resumed after the interruption of the reading operation of the optical recording medium, the read-only optical recording medium capable of surely connecting to the position before the interruption and reading the optical recording medium is provided. The purpose is to provide a management method.
