DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus having a function suitable for reproducing and managing information recorded on a mini disc (MD), for example.

[0002]

2. Related Background Art In recent years, mini disks (MD) have been widely used as disk recording media. Information recording on this mini-disc is usually performed using TOC (Table of
This is performed while adding management information called “content”. Specifically, when music information (song) is recorded, T
A track number is added as OC, and the title of the music information is recorded as user management information (UTOC). During playback, for example, UT
By specifying the track number while checking the OC information, the desired music information is reproduced and output.

[0003]

The information recorded on the MD is erased by erasing the management information (TOC, UTOC) added to the information to be erased. For this reason, there is a problem that it is not possible to restore the recording information once subjected to the erasing operation, and it is impossible to temporarily remove the recording information from the reproduction target. For example, if you do not want to play a song in the recorded music information (songs) so much, but do not want to delete it, temporarily remove the song from the playback target and play it as necessary The process of returning to the target could not be performed.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an MD capable of temporarily excluding recorded information from being reproduced and reproducing / reconstructing the recorded information as necessary. It is an object of the present invention to provide a recording / reproducing apparatus suitable as a recording / reproducing apparatus.

[0005]

In order to achieve the above-mentioned object, in a recording / reproducing apparatus according to the present invention, erasing of recorded information in an MD is performed by erasing management information, and a tune which is a main body of the recorded information is erased. It focuses on not directly erasing itself, and when a hold intended to temporarily exclude recorded information from a target for temporary reproduction is selectively instructed, a specific code is added to the management information of the recorded information. The recording information to which the specific code is added is excluded from the reproduction target. Then, when the return of the reserved recording information is selectively instructed, the specific state added to the management information of the recording information is deleted to return to the original state.

According to a second aspect of the present invention, in particular, the specific code is added to the title information (UTOC) in the management information, and the exclusion of the record information to which the specific code is added from the reproduction target is excluded. It is characterized in that a series of track numbers is assigned only to title information to which no specific code is added.

Further, according to the third aspect of the present invention, the specific code added to the management information of the selected recording information is deleted after the reserved recording information is restored, and then the specific code is not added. It is characterized in that a series of track numbers are re-assigned to the title information to perform the operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a recording / reproducing apparatus according to an embodiment of the present invention will be described with reference to the drawings. First, a schematic configuration of an MD recording / reproducing apparatus (recording / reproducing machine) will be briefly described with reference to FIG. 1. An MD 1 serving as an information recording medium is mounted on a turntable 3 that is driven to rotate by a spindle motor 2. The recording information is optically written (recorded) and read (reproduced) by an optical pickup 4 which is rotated and is provided movably in the radial direction. The optical pickup 4 is scanned by the feed motor 5 and positioned with respect to the MD 1.

The optical pickup 4 uses the MD 1
Is amplified by the RF amplifier 6 and then read out from the EFM / CIRC decoder 7 and the ATI.
The output is output to the P decoder 8, and a part of the output is fed back to the servo processor 9. The servo processor 9 basically controls the rotation of the spindle motor 2 and the operation of the feed motor 5 in response to a command from a system controller 10, and at the same time, based on the reproduction output from the RF amplifier 6, M by optical pickup 4
The tracking of D1 is controlled.

The ATIP decoder 8 obtains TOC data, which is management information in the information read from the MD 1, and supplies the TOC data to the system controller 10. The EFM / CIRC decoder 7 outputs the TOC data from the MD 1. It decodes and reproduces the music that is the information body inside. Recorded information decoded and reproduced through the EFM / CIRC decoder 7 is stored in a shockproof memory.
Signal missing (sound skipping) given to the controller 11 and using the DRAM (memory) 12 under the controller 11
Is compensated for. After that, the recorded information subjected to the signal loss compensation is subjected to the restoration of the absolute time (time axis) via the ATRAC decoder 13 and then to the D / A converter 14.
Is reproduced and output via.

An operation unit 15 having a display, a switch, etc.
Indicates a track number or a song name, which is management information (TOC) associated with the information recorded on the MD1,
Instructions from the user with respect to the display information, for example, instruction information such as reproduction, stop, fast forward, recording, erasing, and holding described later are input. The system controller 10 controls the operations of the above-described units in accordance with the instruction information from the operation unit 15, and executes a series of operations including recording information on the MD 1 and reproducing the information.

A feature of the present invention in the recording / reproducing apparatus configured as described above is that, as shown in FIG. 2, the information (musical music) recorded on the MD1 is temporarily reproduced from the object to be reproduced. When exclusion, that is, suspension is selectively instructed, a specific code is added to track information and title information such as a song name, which are management information recorded along with the recording information, and the recording with the specific code added is performed. The point is that information is temporarily excluded from reproduction targets.

More specifically, as shown in FIG. 2, the title of the recording information to which a series of track numbers is added is "AAA".
.. Are indicated as “BBB”, “CCC”, “DDD”..., For example, when the reservation of the recording information (song) of the track number [2] is selectively instructed, the specific code “BBB” for the information title “BBB” “#” Is added to the beginning of the name, and is changed to “#BBB”. Then, the title information with the specific code “#” added at the beginning thereof is excluded from the reproduction target, and the track number is re-assigned only to the remaining title information, whereby the recording information specified and designated above is obtained. On hold.

When the recording information held in this manner is returned as a reproduction target, as shown in FIG.
For example, when the title information to which the specific code “#” is added is presented, and there is one in which return is instructed,
The specific code added to the head of the title information is deleted. Specifically, when the return of the record information indicated by the title “BBB” is selectively instructed, the specific code “#” added to the title information is deleted, and the original title information “BBB” is returned. . When the processing for the return instruction is completed, the title information is reviewed, and a series of track numbers are re-assigned.

The above-mentioned series of processing for suspension and return is executed, for example, as shown in FIGS. 4 and 5. That is, in the recording information suspension processing, as shown in FIG. 4, while judging whether or not all the title information of the information recorded on the MD1 has been displayed in order (step S1), the titles are displayed one after another. (Step S2). Then, it is determined whether or not a hold instruction is given to the displayed title from the operation unit 15 (step S3). If the hold is instructed, the above-described specific code is added to the title information (step S4). . Such processing is performed in step S1.
Are repeatedly executed for all titles (recording information) under the judgment processing shown in FIG. Then, after the processing for the hold selection instruction is completed, a series of track number resetting processing is executed for the title information to which the specific code is not added (step S5), and the processing procedure is completed.

On the other hand, when the return of the held record information is instructed, as shown in FIG. 5, it is first determined whether or not the search for all the held information has been completed (step S11). The title information to which the code is added is searched (step S12), and the found title information is displayed (step S13). Then, it is determined whether or not a return instruction is given to the title from the operation unit 15 (step S14). If the return instruction is given, the specific code added to the title information is changed. It is deleted (step S15). This process is repeatedly executed for all titles (recording information) to which the specific code is added under the determination process shown in step S11. After the deletion of the specific code from the title information instructed to return is completed, a series of track number resetting processing is executed again for title information to which no specific code is added (step S16), and the processing is performed. Complete the procedure.

Thus, according to the present apparatus having the recording information hold / return function as described above, the recording information to be temporarily excluded from the reproduction target is added to the management information attached to the recording information, that is, the title information. Add a specific sign,
Since the recorded information indicated by the title information to which the specific code is added is excluded from the reproduction target and the reproduction information is managed, it is possible to treat the information to which the specific code is added as apparently not present. Moreover, when it is desired to restore the information, it is only necessary to delete the specific code, so that the restoration process can be executed very easily.

Therefore, when it is desired to temporarily exclude a song that the user does not want to hear so much from the playback target, the song (recording information) is once copied (dubbed) to another recording medium and stored. Although only the method of erasing the song could be taken, according to the above-described device,
This can be simplified and temporarily suspended without erasure, and can be restored as needed. Therefore, the held record information can be treated as apparently not recorded, and can be returned to the original state as needed, so that the handling property is improved. That is, it is possible to effectively save temporarily unnecessary recording information. In particular, since the recording information is suspended by adding a specific code to the title information, and the recording information is restored by deleting the specific code, the original information is not lost at all. There are advantages.

When an MD to which the above-mentioned specific code is added is reproduced using a recording / reproducing apparatus or a reproduction-only apparatus which does not have the above-mentioned functions, even when the title is displayed, even the specific code is used. Although it is displayed, the recorded information itself can be reproduced, so that there is no substantial problem such as a trouble in operation. Further, since the track number is reset as described above, the track number can be used for reproduction while maintaining the above-mentioned hold state.

The present invention is not limited to the above embodiment. For example, when restoring the held record information,
By displaying the recording time of the information to which the specific code is added, or by reproducing the music, it is possible to present the user with information on whether or not to return to the original state. As the specific code, generally, a code not used as title information may be used.
The number is not particularly limited. Further, a specific code may be added to the end of the title information. In addition, the present invention can be modified and implemented in various forms without departing from the gist thereof.

[0021]

As described above, according to the present invention, a specific code is added to the management information for recording information that is to be temporarily excluded from the reproduction target, and the information to which the specific code is added is reserved. Since it is excluded from the reproduction target as having been performed, and is returned to the reproduction target by deleting the specific code, management of the information recorded on the recording medium is facilitated,
A great effect in practical use such as simplification of the handling can be obtained. Moreover, since the processing control itself is simple, there is no burden in configuring the apparatus as hardware, and the compatibility of the recording medium with an apparatus without a hold function can be maintained. Is played.
