Abstract

PROBLEM TO BE SOLVED: To enable music edition work with simple operation by storing the data reproduced from a recording medium in a first memory means, storing content information and recording track numbers into a second memory means, dividing the recording tracks as different track numbers and executing prescribed processing according to the effective and non-effective setting assigned by an input means. SOLUTION: When music A changes to music B, a system controller 13 writes the end address of the first track and the start address of the second track into a buffer and the track number 2 into an erasure track buffer by the information from a level detecting circuit 24. When the music B changes to the music C, the system controller 13 similarly writes the start address of the third track into the buffer and the track number 3 into the erasure track buffer. When a button 22b is operated again after the operation of an enter button 22b during the input of the music C, the third track becomes effective and the track number is not left in the erasure track buffer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an MD recording / reproducing apparatus using an MD as a recording medium will be described as an embodiment of the present invention.

1. Basic Configuration First, the overall configuration of an MD recorder according to an embodiment of the present invention, and a U-TOC in which table of contents information of recording data is recorded
An operation of recording and erasing recording data using information will be described. FIG. 1 shows one embodiment of the present invention, M
FIG. 1 is an overall configuration diagram of a D recorder. A magneto-optical disk (MD) 1 housed in a cartridge case 2 is mounted on a turntable 3 and recorded / recorded by a spindle motor 4.
Rotated during playback. Optical pickup 5 is MD1
On the other hand, during recording, a high-level laser beam for heating a recording track is irradiated, and at the time of reproduction, a low-level laser beam for detecting a recording signal by reflected light is irradiated.
The optical pickup 5 can be moved in the disk radial direction by a slide motor 6. The magnetic head 7 is arranged at a position facing the optical pickup 5 with the MD 1 interposed therebetween. At the time of recording, an EFM (Eightto Fourteen M
odulation) / ACIRC (Advanced Cross Interleave)
(Read-Solomon Code) A magnetic field modulated by data input from the modulation / demodulation circuit 10 is generated by the head drive circuit 8 and applied to the MD 1.

At the time of reproduction, a recording signal recorded on the MD1 is detected by the optical pickup 5, and the detected signal is amplified by the head amplifier 9 and then subjected to arithmetic processing to reproduce RF signal, tracking error signal, focus error. A signal and an address signal are extracted. Extracted reproduction RF
The signal is input to the EFM / ACIRC modulation / demodulation circuit 10 and demodulated. Further, the tracking error signal and the focus error signal are input to the servo control circuit 11. The servo control circuit 11 performs arithmetic processing on the tracking error signal and the focus error signal input from the head amplifier 9, converts the signal into a control signal suitable for the control system of the optical pickup, and outputs the control signal. Also, the system controller 13
And outputs a control signal for controlling the optical pickup and a control signal for controlling the spindle motor 4 and the slide motor 6 in response to a command such as a track jump output from the controller.
The address signal is input to the address decoder 12, demodulated and converted into address information of a recording data part, and then together with the information of the recording data demodulated by the EFM / ACIRC modulation / demodulation circuit 10, the system controller 13
Supplied to The reproduced RF signal demodulated by the EFM / ACIRC modulation / demodulation circuit 10 is temporarily written into a recording circuit (memory) 15 by the memory controller 14. The speed at which the signal detected by the optical pickup 5 is transferred to the recording circuit 15 is 1.4 Mbit / sec.

The data written in the recording circuit 15 is 0.3
Mbits are read out at the rate of every second, and ATRAC (Adapti
ve Transform Acoustic Coding) is input to the modulation / demodulation circuit 16. Here, the compressed and recorded data is demodulated as expanded audio signal data. The expanded audio data is converted into an analog signal by a DA converter (digital-analog converter) 17, and then output as audio from a reproduction signal output terminal 18. When an analog signal of an audio signal reproduced by a CD player or an audio signal received and demodulated by a tuner is recorded on the MD1, the analog signal is input to a recording signal input terminal 19, and an analog-to-digital (AD) converter (analog-digital) is input. 44.1 kHz sampling at 20)
After being converted to 16-bit quantized recording data, ATRA
The signal is input to the C modulation / demodulation circuit 16.

The recording data is subjected to audio compression processing in an ATRAC modulation / demodulation circuit 16 and then to a memory controller 14
Is temporarily written into the recording circuit 15, and
5 is read by the memory controller 14 and the EF
The signal is input to the M / ACIRC modulation / demodulation circuit, subjected to modulation processing, and then input to the head drive circuit 8. The head drive circuit 8 generates a magnetic field with the magnetic head 7 according to the input recording data and applies the magnetic field to the MD 1. At this time, the system controller 13 supplies a control signal to the servo drive circuit 11 to irradiate the optical pickup 5 with a high-level laser beam for heating the recording track. The output device (display unit) 21 is a device for displaying the state of the MD recorder, and displays, for example, the number of a track performing a reproducing operation and the elapsed time. The input device (operation unit) 22 is a means for the user to operate the MD recorder, and includes buttons and the like operated by the user when starting or ending the reproduction operation or the recording operation. When performing a recording / reproducing operation on the MD1, it is necessary to read out or update the table of contents information recorded on the MD1, that is, the U-TOC (user TOC).

In the U-TOC sector 0, information for managing table of contents information such as a track (song) recorded in the user recording area and an address indicating a recordable area is recorded. FIG. 2 shows M according to an embodiment of the present invention.
4 shows the format of U-TOC sector 0 of the D recorder. In FIG. 2, FirstTNO is the first track number of the MD, and LastTNO is the last track number. P-TNO1, P-TNO2, P-TNO3. . .
P-TNO 255 indicates a track number recorded on the MD, and a pointer indicating a part slot assigned to each of the track numbers 1 to 255 is recorded. In each part slot indicated by the pointer, a start address, an end address, a track mode, and link information, which are physical addresses of a recording information unit (track), are stored. Start address, end address is M
When the link information is the physical address information on D and there is no link, the area indicated by the start address and the end address forms one track. When the link information has a link, a plurality of parts from the start address of the head part slot to other part slots indicated by the link information are sequentially combined, and the link information reaches a part slot where there is no link. One track is composed of the slot area. Here, the track mode is mode information of a track representing stereo monaural or the like. In the P-FRA, a pointer indicating a recordable area on the MD is recorded. In P-EMPTY, a pointer indicating an unused part slot is recorded.

Next, a U-TOC processing method for recording (recording) an audio signal on an MD will be specifically described. FIG. 3 shows an example in which table of contents information of UTOC sector 0 before recording is recorded. FIG. 4 shows an example in which table of contents information of UTOC sector 0 after recording is recorded. For example, consider a case where a fifth track is newly recorded on an MD recorded up to four tracks.

First TNO is the first track,
LastTNO is the fourth track. This indicates that the first to fourth tracks have been recorded. P-TNO1 is 1. This is a pointer to the part slot number, and the physical address of the MD that records the start address and end address of the first track is recorded in the part slot 1 indicated by the pointer. In this embodiment, the start address of the MD of the first track is A and the end address of the MD is B. Similarly, the second track has a start address C, an end address D,
The third track has a start address E and an end address F,
The fourth track has a start address of G and an end address of H.

In this example, the fifth track to the 255th track do not exist, and are all 0 from P-TNO5 to P-TNO255. The recordable area is P-FR
The address exists from the address I to the address Z recorded in the part slot 255 indicated by the pointer of A. The unused area is a part slot 25 linked in order from the part slot 5 indicated by the P-EMPTY pointer.
Up to 4. Here, when a new audio signal is recorded on the fifth track, P-TNO5 is assigned to the index information of the new track. Judging from the P-EMPTY pointer, the part slot 5 is set to the part slot number of P-TNO5, and the P-EMPTY pointer is updated to 6. Then, the start address I and the end address J on the MD on which the fifth track is recorded are written in part slot number 5, and La is set so that the last track is the fifth track.
Update stTNO to 5. At this time, the recordable area changes from the address K to Z, and the start address of the part slot 255 indicated by the pointer of the P-FRA is updated to the address K. FIG. 4 shows the U-TOC after the fifth track has been recorded. The broken lines are the portions updated from FIG. As described above, by updating or additionally recording the table of contents information of the recording data in the U-TOC, the fifth track recorded on the MD is managed so that it can be reproduced.

Next, a U-TOC processing method for erasing (erasing) a recorded track will be specifically described. FIG. 5 shows an example in which the table of contents information of UTOC sector 0 before the erasing process is recorded. FIG. 6 shows an example in which the table of contents information of the UTOC sector 0 after the erase process is recorded. For example, consider the case where the third track of the MD recorded up to the fourth track is deleted.

The recorded contents of UTOC sector 0 before the erase process are as shown in FIG. First TNO is the first track, and Last TNO is the fourth track. This shows that the first to fourth tracks are recorded. The pointer of P-TNO1 is 1. This indicates that the first track is composed of part slot number 1. Further, the physical address of the MD is recorded in the part slot number 1, and the start address and the end address are recorded. That is, in the present embodiment, the first track is a track that starts at address A of the MD and ends at address B. Similarly, the second track starts with a start address C, the end address is D, the third track has a start address E and an end address F, the fourth track has a start address G, and an end address H.

In this example, the fifth track to the 255th track do not exist, and all P-TNO5 to P-TNO255 are 0. The recordable area is P-FR
The address exists from the start address I to the end address Z recorded in the part slot number 255 indicated by the pointer A.
Unused part slots are part slot numbers 5 to 254 linked in order from part slot number 5 indicated by the pointer of P-EMPTY.

When erasing the third track, P-TNO
The U-TOC is updated so that the area from the start address E to the end address F of the part slot number 3 indicated by the pointer 3 becomes a recordable area. That is, P-TNO3
Is linked to the P-FRA. Specifically, the part slot number indicated by the P-TNO3 pointer is recorded in the link information recorded in the part slot number 255 indicated by the P-FRA pointer. . As a result, the area of the start address and the end address recorded in the part slot number 3 is registered as a recordable area. Next, the recording area of the current fourth track is newly added to the third track.
To update and register as a track, the pointer of P-TNO3 is updated to the pointer of P-TNO4,
The pointer of TNO4 is set to 0. Next, LastTNO is updated to 3 so that the last track is the third track. Thus, the last track of the MD is 3, and the third track has been erased.

2. First Embodiment Taking an MD recorder shown in FIG. 7 as an example of a recording / reproducing apparatus according to a first embodiment of the present invention, an audio signal received and demodulated by a tuner is input to the MD recorder and specified by a user operation. An example will be described in which only the music piece is left as recording data on the MD.

FIG. 7 is an overall configuration diagram showing an MD recorder according to an embodiment of the present invention. FIG. 7 shows a button (pick recording button) 22 for setting a mode for selecting validity / invalidity of recording as an input unit 22 for selecting validity / invalidity of recording in the conventional MD recorder described in FIG.
a, button for setting recording validity / invalidity (enter button) 22b, button for stopping recording (stop button)
22 is an MD recorder configured by adding a storage unit B23 for storing validity / invalidity of recording for each music piece and a level detection circuit 24 for determining an input information unit (between music pieces of an audio signal). It is assumed that an analog signal received and demodulated by a tuner not explicitly shown in FIG. 7 is input to the recording signal input terminal 19.

The storage section B23 stores the start address and end address of the recording data recorded on the MD and information of a specific information unit, that is, valid or invalid track number set for a specific track (song). Written by controller 13. Here, an operation state in which it is possible to set whether or not to leave the information unit as recording data for each information unit (track) is referred to as a pick-rec mode for explanation, and a track set not to be retained as recording data is deleted for explanation. Call it a truck. The storage unit in which the erased track information is stored is referred to as an erased track buffer, and the storage unit in which the start address and end address information of the recorded data is stored is referred to as a U-TOC buffer. Although the storage unit B23 is used as an erase track buffer, a part of the storage unit B23 may be used as a U-TOC buffer at the same time.

A pick recording button 22a which is an operation button for setting the pickup recorder to enter / cancel the pick recording mode, and an enter button 22 which is an operation button for deciding whether or not the track is to be left in the MD for each track.
b, a stop button 22 which is an operation button for stopping various operations and for stopping a recording operation in the pick recording mode.
c is provided on the operation unit of the MD recorder.

First, the MD that can be recorded by the user is M
When the MD recorder is mounted on the D recorder and the pick recorder button 22a is pressed, the MD recorder enters the pick recorder mode. When the pick-up mode is entered, the MD recorder starts recording the input signal on the mounted MD. At this time, the system controller 13 sets M to start recording.
The start address which is the physical address on D is written into the storage unit B23 of the U-TOC buffer.

At the same time, the track number on the MD is written into the storage section B23 of the erase track buffer. In this function, the track is invalidated unless the input button for valid / invalid of the recording data input during the pick recording mode is input, and the recording data being recorded is not left as recording data. It is intended to be. Also, even if the track is enabled when there is no input of the enable / disable input button, the same effect can be realized by clearing the track number stored in the erased track buffer. Becomes

Next, the memory controller 14 is controlled to transfer the recording data compressed by the ATRAC modulation / demodulation circuit 16 to the storage unit 15 and transfer the recording data transferred to the storage unit 15 and stored at a predetermined data transfer rate. Read EF at
The data is transferred to the M-ACIRC modulation / demodulation circuit 10. The servo drive circuit 11 controls the spindle motor 4, the optical pickup 5, and the slide motor 6 to record data on the MD.

When the system controller 13 detects a change in the information unit based on the output of the level detection circuit 24, that is, the interval between the tunes of the input audio signal, the system controller 13 records the recording data corresponding to the input signal until the interval between the tunes is detected to the MD. The storage unit 23 uses the last physical address of the recorded area as the end address.
Write to. Thus, the area indicated by the start address and the end address can be treated as one track. Further, the address following the end address is written in the storage unit 23 as the start address of the next track.

When the user presses the enter button 22b during the pick recording mode to set the corresponding track as valid, the track number is deleted from the erase track buffer. Also, if the user presses the Enter button again after enabling this track,
The track number is written into the erased track buffer again using this track as the erased track.

As a series of operations of the present invention, five pieces of music A, music B, music C, music D, and music E received and demodulated by the tuner are input to the MD recorder shown in FIG. , Set song D as valid, and finally set song B and song D to MD
The remaining examples will be described with reference to FIGS. 7, 8, 9 and 10. FIG. Here, it is assumed that the MD recorder is mounted with a blank disc capable of recording the entire user recordable area.

FIG. 8 shows M in the first embodiment of the present invention.
It is a figure which shows the signal input into a D recorder, and the information written into the memory | storage part B23 by a user's operation.
FIG. 9 is a flowchart (1) for explaining the operation in the first embodiment of the present invention. FIG. 10 is a flowchart (2) for explaining the operation in the first embodiment of the present invention, and shows a flowchart showing the control contents of the system controller 13. 9 and 10, the music A of the audio signal received and demodulated by the tuner is an MD.
When input to the recorder, when the user presses the pick REC button 22a (S1), the pick REC mode is turned on (S2), the erase track buffer is cleared (S3), and the song A is set as the first track in the pick REC mode. Recording starts (S4). Then, the start address A of the first track is set to U-
Write to the TOC buffer (S5) and register track number 1 in the erase track buffer (S6). The addresses and track numbers stored in the U-TOC buffer and the erase track buffer are shown in (1) of FIG.

When the input signal changes from music A to music B, the system controller 13 determines that the track (music) has changed based on the information output from the level detection circuit 24 (S1).
2), the end address B of the first track and the next track,
That is, the start address C of the second track is written in the U-TOC buffer (S21), and the track number 2 is written in the erase track buffer (S22). Also, since the user did not operate the enter button 22b while the song A was being input, the first track was invalidated and the track number is left in the erased track buffer. The addresses and track numbers stored in the U-TOC buffer and the erase track buffer are shown in (2) of FIG.

When the user operates the enter button 22b while the song B is being input (S10), the system controller 13 determines whether the current track number has been registered in the erased track buffer (S19). If registered, the current track number is deleted from the erased track buffer (S20). The addresses and track numbers stored in the U-TOC buffer and the erase track buffer are shown in (3) of FIG.

When the input signal changes from music B to music C, the system controller 13 determines from the information output from the level detection circuit 24 that the track (music) has changed (S1).
2), the end address D of the second track and the next track,
That is, the start address E of the third track is written in the U-TOC buffer (S21), and the track number 3 is written in the erase track buffer (S22). Since the user operated the enter button 22b while the song B was being input, the second track is valid and the track number is not left in the erased track buffer. The addresses and track numbers stored in the U-TOC buffer and the erase track buffer are shown in (4) of FIG.

When the user operates the enter button 22b while the song C is being input (S10), the system controller 13 determines whether or not the current track number has been registered in the erased track buffer (S19). If registered, the current track number is deleted from the erased track buffer (S20). The addresses and track numbers stored in the U-TOC buffer and the erase track buffer are shown in (5) of FIG.

Thereafter, when the user operates the enter button 22b again while the music C is being input, the user enters (S
10), the system controller 13 determines whether the current track number has been registered in the erased track buffer.
(S19) If not registered, the current track number is written into the erased track buffer again (S23). U above
The addresses and track numbers stored in the TOC buffer and the erase track buffer are shown in (6) of FIG.

When the user operates the enter button 22b again after the user operates the enter button 22b while the music C is being input, the third track becomes valid and the track number is not left in the erased track buffer.

It is assumed that the above operation is performed up to the song E, and the user operates the stop button 22c to stop the recording in the middle of the song E. As a result of the user setting the music B and the music D as valid, the contents of the address and the track number stored in the U-TOC buffer and the erased track buffer are as shown in FIG.

When the system controller 13 detects the input of the stop button 22c and stops recording (S13),
First, the U-TOC is updated based on the contents of the addresses stored in the U-TOC buffer for all the recorded tracks, and the updated U-TOC is stored in the U-TOC area of the MD.
Information is recorded (S14), and all the recorded tracks are recorded data on the MD.

Next, the system controller 13 confirms whether the information of the erase track set by the user can be directly executed as the erase process. As a confirmation method, for example, “Pick Rec O
K? Is output, and the user enters "P
kick Rec OK? Is displayed,
Enter OK or NO from the operation unit. (S15), (S16)

Here, "Pick Rec OK?" Is input from the operation unit while the display is displayed, it is denied that the erase processing is performed with the information of the erased track, and the erase processing is not executed.
Clear all erase track buffers. (S18) As a result, all the recorded tracks are left as recording data in the MD.

In addition, "Pick Rec OK?" Is displayed on the display, and if OK is input from the operation unit,
The erasing process is permitted with the information of the erasing track unchanged, and the erasing process is performed by updating the U-TOC information related to the track stored in the erasing track buffer to a recordable area. Execute. (S17) At the same time, all the erased track buffers are cleared. (S18) As a result, only the track (song) set as valid by the user is left as recording data in the MD.

If the pick-rec button 22a is pressed during recording of an input signal in the pick-rec mode, the pick-rec mode is canceled, all erased track buffers are cleared, and recording is continued. It is possible to make the same operation as the normal recording operation. (S24)

Reference numeral 2f denotes an operation button for designating that the track indicated by the numeric keypad 22d is not left as recording data.
The music calendar 21a is a display for displaying a track number and is provided in the display unit.

Valid / invalid is set for each input track (song), after the recording is stopped, the U-TOC is updated, and the erase process is performed with the information of the erased track buffer set by the user. Before outputting the confirmation message to the output device 21, all the track numbers once recorded are displayed on the output device 21, and the track numbers set as valid among them are displayed on the music calendar 21a. Here, if the OK button 22e is operated while the track number as the numeric keypad 22d is specified and the track number is blinking displayed on the music calendar 21a, the track is valid regardless of the information in the erased track buffer. If the cancel button 22f is operated while the track number is blinking displayed on the music calendar 21a, the track is updated to be invalid regardless of the information in the erased track buffer.

A series of operations, five songs A, B, C, D and E received and demodulated by the tuner are input to the MD recorder shown in FIG.
Is set to be valid, the music C is changed to valid, and the music D is changed to invalid, and finally the music B and the music C remain in the MD.
This will be described with reference to FIGS. 2, 13, 14 and 15.

FIGS. 12 and 13 show signals input to the MD recorder according to the second embodiment of the present invention, information written in the storage section B23 by user operation, and contents displayed on the music calendar 21a. FIG. FIGS. 14 and 15 are flowcharts showing the control contents of the system controller 13 according to the second embodiment of the present invention.

It is assumed that the MD recorder is loaded with a blank disc capable of recording the entire user recordable area. Song A received / demodulated by tuner is MD
When the input is made to the recorder, if the user presses the pick rec button 22a, (S31) the pick rec mode is turned on (S32), the erase track buffer is cleared, and (S3
3) Start recording with song A as the first track in pick-rec mode. (S34) Then, the start address A of the first track is written in the U-TOC buffer, and (S35) the track number 1 is registered in the erase track buffer. (S36)

The contents of the addresses and track numbers stored in the U-TOC buffer and the erased track buffer and the display of the music calendar are as shown in FIG. When the input signal changes from song A to song B, the system controller 13 determines that the track (song) has changed based on the information supplied from the level detection circuit 24, and (S48) the end address B of the first track and the next address. , The start address C of the second track is written to the U-TOC buffer, and (S49) Track number 2 is written to the erased track buffer. (S50) If the user does not operate the enter button 22b while the song A is being input, the first track is invalidated and the track number is left in the erased track buffer. The contents of the addresses and track numbers stored in the U-TOC buffer and the erase track buffer and the display of the music calendar are as shown in FIG. 12 (2).

When the user operates the enter button 22b while the music B is being input (S40), the system controller 13 determines whether or not the current track number has been registered in the erased track buffer (S41). If registered, the current track number is deleted from the erased track buffer, and (S42) the track number 2 is displayed on the music calendar 21a. (S43) The contents of the address and track number stored in the U-TOC buffer and the erased track buffer and the display of the music calendar are as shown in (3) of FIG.

The contents of the addresses and track numbers stored in the TOC buffer and the erase track buffer and the display of the music calendar are as shown in (4) of FIG.

In this state, that is, when the enter button 22b is operated in a state where a specific track number is not designated by the numeric keypad 22d (S62), the system controller 13 performs the erase process with the information of the erase track set by the user. Check if you can. As a confirmation method, for example, “PickR
ec OK? Is output and the user is prompted to select "Pick Rec OK?" Is displayed, "OK" or "NO" is input from the operation unit. (S63)

Here, "Pick Rec OK?" Is input from the operation unit while the display of "" is displayed, it is denied that the erase process is performed with the information of the erased track as it is, and the information of the erased track is returned to a state where it can be changed. As a result, all the recorded tracks are left as recording data in the MD.

Here, "Pick Rec OK?" Is input from the operation unit while the display is displayed, the erasing process is permitted with the information of the erased track unchanged, and the U-TOC information related to the track stored in the erased track buffer is displayed. The erase process is executed by performing an operation of updating to a recordable area. (S65) At the same time, all the erased track buffers are cleared. (S66) As a result of the above operation, only the tracks set as valid by the user are left as recording data in the MD.

4. Third Embodiment A third embodiment, which is a modification of the first embodiment, will be described. Here, an MD recorder shown in FIG. 16 is taken as an example of a recording / reproducing apparatus according to a third embodiment of the present invention, and while a song recorded on the MD is reproduced, only a specific song is recorded on the MD by a user operation. An example of erasing from recorded data will be described.

FIG. 16 shows an example in which the MD recorder according to the first embodiment of the present invention shown in FIG. This is an MD recorder provided with a pick play button 22g having a function of setting invalidation.

Here, an operation state in which the information unit to be reproduced can be set to be erased from the recording data for each information unit (track) to be reproduced is called a pick play mode for the sake of explanation, and is set to be erased from the recording data. The erased track is called an erased track for the sake of explanation, and an area where the erased track information is written in the storage unit B23 is called an erased track buffer for the sake of explanation.

A pick play button 22 which is an operation button for setting a pick play mode on the MD recorder.
g, an enter button 22b as an operation button for setting whether or not to leave the MD for each track, and a stop button 22c as an operation button for stopping various operations and stopping the reproduction operation in the pick play mode.

When the user mounts the MD on which one or more tracks (songs) are recorded on the MD recorder and presses the pick play button 22g, the MD recorder enters the pick play mode. When you enter the pick play mode,
The MD recorder starts reproducing the audio signal recorded on the mounted MD. At this time, the system controller 13 clears all the erase track buffers. This is so that the recording data recorded on the MD reproduced during the pick play mode is valid unless the input button for valid / invalid is input, and the recording data being reproduced is recorded. The purpose is to leave it as data. Further, even if the function of invalidating the track is performed if there is no input of the valid / invalid input button, the same effect can be realized by writing the track number to be reproduced in the erased track buffer. .

Then, the spindle motor 4, the optical pickup 5, and the slide motor 6 are controlled by the servo drive circuit 11 to read out recorded data from a predetermined position, and the head amplifier 9 and the EFM / ACIRC modulation / demodulation circuit 10 extract and demodulate the data. The reproduced RF signal thus obtained is stored in the memory controller 14.
And temporarily writes it to the storage unit (memory) 15. The data written and stored in the storage unit 15 is read at a predetermined data transfer rate, and the compressed signal input to the ATRAC modulation / demodulation circuit 16 is expanded and demodulated as audio data. The expanded audio data is converted into an analog signal by the DA converter 17 and then output from the reproduction signal output terminal 18 as an audio signal. It is assumed that an audio amplifier and a speaker (not shown in FIG. 16) are connected to the reproduction signal output terminal, and the user listens to the audio signal reproduced from the speaker.

During the pick play mode, when the user presses the enter button 22b to set the designated track as an erasure track to be invalid, the system controller 13 writes the track number into the erasure track buffer. Also, after disabling this track,
If the user presses the enter button 22b again,
This track is made valid, and the track number is deleted from the erased track buffer.

This series of operations is performed from the first track to the fifth track.
The user sets the second track and the fourth track to invalid while reproducing the MD on which the tracks are recorded by the MD recorder shown in FIG. 16, and only the first, third, and fifth tracks record the MD. An example that remains as data is shown in FIG.
This will be described with reference to FIGS. 17, 18 and 19. FIG.
FIG. 14 is a diagram illustrating a signal input to an MD recorder and information written to a storage unit B23 by a user operation according to a third embodiment of the present invention. FIGS. 18 and 19 show a system controller 1 according to the third embodiment of the present invention.

It is assumed that an MD recording up to a track is mounted. When the user presses the pick play button 22g (S81), the pick play mode is turned on (S82), the erased track buffer is cleared (S83), and reproduction is started from the first track in the pick play mode (S84). The contents of the track number stored in the erase track buffer are as shown in (1) of FIG.

Address decoder 12, EFM / ACIR
When the system controller 13 detects that the reproduction of the first track is completed based on the address information input from the C modulation demodulation circuit 10 (S92), the next second track is reproduced (S100). Also, since the user did not operate the enter button 22b while the first track was being reproduced, the first track was valid and its track number was not written in the erased track buffer. The contents of the track number stored in the erase track buffer are as shown in (2) of FIG.

When the user operates the enter button 22b while the second track is being reproduced (S90), the system controller 13 determines whether the current track number has been registered in the erased track buffer (S98). ,
If not registered, the current track number is written to the erase track buffer (S101). The contents of the track number stored in the erase track buffer are as shown in (3) of FIG.

Address decoder 12, EFM / ACIR
When the system controller 13 detects that the reproduction of the second track is completed based on the address information input from the C modulation demodulation circuit 10 (S92), the reproduction of the next third track is started (S100). When the user operates the enter button 22b while the second track is being reproduced, the second track is invalidated and its track number is left in the erased track buffer. The contents of the track number stored in the erase track buffer are as shown in (4) of FIG.

The above operation is performed up to the fifth track, and the fifth track
During playback of a track, the user presses the stop button 22C.
Is operated to stop the playback. User is second or fourth
As a result of setting the track as invalid, the contents of the track number stored in the erased track buffer are as shown in (5) of FIG.

When the system controller 13 detects the input of the stop button 22c and stops the reproduction (S93),
It is confirmed whether the information of the erase track set by the user can be directly executed as the erase process. As a confirmation method, for example, “Pick Platform” is displayed on the display unit 21.
y OK? Is output, and the user is asked "Pick Play OK?" Is displayed, "OK" or "NO" is input from the operation unit. (S94)

Here, "Pick Play OK?" 』
Is input from the operation unit while the display of is displayed, it is denied that the erase process is performed with the information of the erased track, and the erase process is not executed.
Clear all erase track buffers. (S97) As a result, the erase processing is not performed on all the tracks.

Also, "Pick Play OK?" Is input from the operation unit while the display is displayed, the erasing process is permitted with the information of the erased track unchanged, and the U-TOC information related to the track stored in the erased track buffer is displayed. The erase process is executed by performing an operation of updating to a recordable area. (S96) At the same time, all the erased track buffers are cleared. (S97) As a result, only the track (song) set as valid by the user is left as recording data in the MD.

If the pick play button 22g is pressed during playback in the pick play mode (S9
1), the pick play mode is canceled, the erased track buffer is cleared, and the reproduction is continued, whereby the same operation as the normal reproduction operation can be performed (S102).
