Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording unit editing device.

[0002]

2. Description of the Related Art As a recording unit editing device for editing a recording unit of a recording medium capable of erasing and combining records in a predetermined recording unit, for example, a recording / reproducing function for an MD (mini disk) is used. It is known to be applied to a device having the same. In this case, the recording unit is an MD track, and the editing function is generally divided into tracks (DIVIDE), move (MOVE), and combine (COM).
BINE), erasing all tracks or one track (ALL
/ TRACK ERASE) and input of disc or track title (DISC / TRACK TITL)
E INPUT) and the like are used. Conventionally, in a recorded MD, a track that is no longer heard or is no longer needed is erased by a track erase (TRACK ER
It can be erased by the (ASE) function.

[0003]

However, according to this, once the track is erased, the audio data of the track cannot be restored, so that the track cannot be heard again, which is inconvenient. On the other hand, if the tracks that are no longer heard are left alone, the number of MD tracks will increase in large numbers as the recording is repeated, making track searching and editing troublesome.

In view of the above problems of the prior art, it is an object of the present invention to increase the number of recording units in a recording unit editing apparatus, which is inconvenient when the recording unit is erased again. It is to solve without.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A recording unit editing apparatus according to an embodiment of the present invention is applied to an MD recording / reproducing apparatus, and is capable of erasing and merging recordings for an MD in track units. Is possible. This recording / reproducing apparatus accepts an instruction to perform junk editing, and accepting means for accepting the designation of a track on the MD to be the target of junk editing, and the designated track and the MD on the MD according to the instruction. And a coupling means for coupling with a predetermined track. It should be noted that the predetermined track does not include the one selected by the user as a target of the normal combined editing.

The coupling by the coupling means is performed by coupling the designated track to the predetermined track. That is, the track number of the combined track is the same as the track number of the predetermined track.
The receiving means and the coupling means are composed of a microcomputer of the recording / reproducing apparatus, display means driven by the control thereof, recording / reproducing means, and the like. As the predetermined track, a track having a track number reserved in advance for its use may be used, but here, a track to which predetermined recognition information is added (hereinafter referred to as a “trash can track”). Is used.

The identification information is added by recording the identification information in the UTOC area of the MD. The recognition information is recorded in the second data area of the date / time data area in sector 2 of the UTOC area or the track title area in sector 1 of the UTOC area.
Further, the recognition information includes information indicating the recording method of the track to which the recognition information is added.

Specifically, when recording in the track title area, by recording "JUNK-***" as the recognition information instead of the track title in the normal sense, that track is a trash can track. Can be recognized. "***" is a character string indicating the recording method of the track, "STEREO" (stereo), "MONO" (monaural), "LP2" (long play (double) mode) or "LP4" (long) Play (4 times) mode) enters. "JUNK" represents a meaning such as a trash can.

When recording in the second data area, unique data that is not normally possible is set as the recognition information instead of the second data so that the track is recognized as a trash can track. You can For example, as the seconds data, "61" to "64"
Set either of. "61" to "64" are the recording modes of the respective tracks: stereo, monaural, LP
It is also shown to be 2 or LP4.

Recording of music data on the MD is performed by a plurality of recording methods, that is, "STEREO" (stereo) and "MON".
O "(monaural)," LP2 "(long play (double)
Mode) or "LP4" (long play (4 times) mode). A predetermined track to be combined (hereinafter referred to as "combined track").
Is selected as a track that is the same as the recycle bin track and has the same recording method (recording mode) as the track designated as the target of junk editing. When the track to be combined does not exist, the combining unit adds the above-described recognition information to the track to be edited instead of performing the combination. That is, the track to be edited becomes a new trash can track.

FIG. 1 is a flowchart showing a processing procedure by a junk (JUNK) editing function in the recording / reproducing apparatus. As described above, the junk editing function is to combine an editing track with a trash can track recorded by the same recording method (recording mode) as the track (COMBIN).
E) function. As described above, the trash can track is a track having recognition information for recognizing the trash can track in the UTOC area of the MD in which the track is recorded.

As shown in the figure, the recording / reproducing apparatus accepts an instruction to perform junk editing in step 1, and accepts designation of a track to be subjected to junk editing in step 2, and then in step 3, MD
Information on the UTOC area read from
C information ". ), The recording mode of the designated track (hereinafter referred to as “designated track”) is extracted.
The recording mode is recorded in sector 0 of the UTOC area.

Next, in step 4, referring to the UTOC information, a trash can track of the same recording mode as the designated track is searched from all the tracks. Then, in step 5, it is determined whether or not a corresponding trash truck is found. If found, the process proceeds to step 6, and if not, the process proceeds to step 8.

In step 6, the track number of the designated track is moved to the track number next to the track number of the trash truck searched in step 4 (MOV).
E) Edit. Since pointers to the start address and end address of the music information of each track are recorded in sector 0 of the UTOC area, the track is moved by replacing the pointer in the UTOC information. Next, in step 7, the trash truck and the designated truck are combined (COMBINE).
Edit and proceed to step 9. The combined editing is performed by linking the address information to the music information of each combined track with a pointer, but this combining reduces the total number of track numbers used by one.
That is, the number of empty tracks increases by one.

In step 8, the above-mentioned recognition information is written in the track title or second information area of the designated track in the UTOC information. As a result, the designated track will
It becomes a new trash truck. After this, the process proceeds to step 9.

In step 9, the UTOC information is written in the MD. As a result, the edited result is reflected on the MD, and the processing by the junk editing function is completed.

According to this embodiment, tracks that are no longer heard or are unnecessary can be formally erased by combining them with the trash can track by junk editing. Then, the contents of the formally erased track can be reproduced later by using the trash can track as a search unit. Further, since the tracks that are formally deleted are combined with the trash can track, the number of tracks is not increased and the searching or editing of the tracks is not hindered. Further, since the condition that the recording modes are the same is used as the search condition for the trash can track in step 4, a trash can track can be created for each recording mode.

When the contents of the trash can track are completely unnecessary, the contents of the trash can track can be completely erased by deleting the trash can track by normal erasure editing. At that time, since there is a trash can track for each recording mode, the contents of the trash can track can be erased for each recording mode.

[0027]

As described above, according to the present invention, the designated recording unit is combined with the prescribed recording unit in response to the user's instruction. Therefore, the data itself of the designated recording unit is It is possible to perform a formal erasing by erasing the recording unit while leaving it.
Therefore, it is possible to eliminate the inconvenience that the recording unit cannot be heard again when the recording unit is erased without increasing the number of recording units.
