Description

[0001]
[Industrial application fields]
The present invention relates to a disk recording / reproducing apparatus that records and reproduces sound and the like using, for example, a small magneto-optical disk.
[0002]
[Prior art]
For example, a so-called mini disk (MD) disk system that records and reproduces sound and the like using a small magneto-optical disk has been proposed (see Japanese Patent Application No. 3-27567).
[0003]
In such a mini-disc (MD), recording is conventionally performed sequentially from the inner peripheral side of the disc as shown in FIG. That is, at the beginning of the recording area, there is provided an area of information (TOC: Table Of Contents) indicating the data recording status, followed by data (1), data (2), data (3). Are sequentially provided.
[0004]
However, when such a mini-disc (MD) is used to construct a voice memo device, for example, if one mini-disc (MD) is to be shared by a plurality of users, the above-described inner circumference is used. It is difficult to take correspondence with each user in the recording performed sequentially from the side.
The present invention has been made in view of these points.
[0005]
[Problems to be solved by the invention]
The problem to be solved is that it is difficult to take correspondence with each user when recording is performed sequentially from the inner circumference side, for example, when a plurality of users share the same.
[0006]

A reproduction apparatus characterized by permitting reproduction of data recorded in an area .
[0007]
[Action]
According to this, the recording area of the disc is divided into a plurality of areas, and the operation means corresponding to each division is provided, so that the correspondence with each user can be taken very easily.
[0008]
【Example】
In FIG. 1, reference numeral 1 denotes, for example, an audio signal input terminal. The audio signal from the input terminal 1 is supplied to the A / D converter circuit 2 to form digital data. This data is supplied to the ATRAC encoder / decoder circuit 3 for audio compression, and the encoded data from this circuit 3 is supplied to the 1 Mbit DRAM 5 through the shock proof memory controller 4.
[0009]
Further, a CPU 6 for system control receives the signal from the operation unit 7 and controls the entire apparatus, and displays the control state on the display unit 8. Here, the operation unit 7 is provided with a plurality of operation buttons 71, 0 to 9 numeric buttons 72, and a recording button 73, for example, as shown in the figure.
[0010]
Further, communication is performed between the CPU 6 and the controller 4, and when a predetermined amount of data is accumulated in the DRAM 5, this data is read and recorded. That is, the data read from the DRAM 5 through the controller 4 is supplied to an 8-14 conversion (EFM) and error correction coding (CIRC) encoder / decoder circuit 9 for recording. It is supplied to the head drive circuit 10. Thereby, the magnetic field of the recording head 11 is changed, and the change of the magnetic field is supplied from the upper surface side of the mini disk (MD) 12.
[0011]
Further, a signal from the CPU 6 is supplied to the optical pickup 14 through the servo circuit 13, and laser is emitted from the lower surface side of the mini disk (MD) 12 at a predetermined timing. At this time, the feed motor 15 of the optical pickup 14 and the spindle motor 15 of the mini disk (MD) 12 are controlled and driven by signals from the servo circuit 13. The audio signal supplied to the input terminal 1 in this way is recorded on the mini disk (MD) 12.
[0012]
On the other hand, at the time of reproduction, a signal from the optical pickup 14 is supplied to the encoder / decoder circuit 9 through the RF amplifier 17. Further, a signal from the RF amplifier 17 is supplied to the address decoder 18, and a cluster number corresponding to the above absolute address is determined. The cluster number from the address decoder 18 is supplied to the CPU 6 through the encoder / decoder circuit 9. As a result, the optical pickup 14 is moved to a recording area where desired data is recorded.
[0013]
Further, the data decoded by the encoder / decoder circuit 9 is supplied to the 1M bit DRAM 5 through the controller 4. When a predetermined amount of data is accumulated in the DRAM 5, this data is read out by a signal from the CPU 6, supplied to the encoder / decoder circuit 3, and the data decoded by the circuit 3 is converted into the D / A converter circuit 19. The analog signal is taken out to an audio signal output terminal 20, for example. In this way, the data recorded on the mini-disc (MD) 12 is reproduced and taken out to the output terminal 20.
[0014]
Further, in this apparatus, the recording area of the mini disk (MD) 12 is divided into a plurality of areas A, B, C... As shown in FIG. Further, the plurality of operation buttons 71 described above are set corresponding to the areas A, B, C.
[0015]
Thus, for example, when an audio signal is input to the input terminal 1 while pressing the operation button 71A and the recording button 73, the audio signal is converted into data (1) and recorded in the area A of the mini disk (MD) 12. . Next, when an audio signal is input to the input terminal 1 while pressing the operation button 71B and the recording button 73, the audio signal is converted into data (2) and recorded in the area B of the mini disk (MD) 12. Further, when an audio signal is input to the input terminal 1 while pressing the operation button 71A and the record button 73, the audio signal is converted into data (3) and the data (1) in the area A of the mini-disc (MD) 12 is stored. Recorded later.
[0016]
Further, when the operation button 71A is pressed to the mini-disc (MD) 12 thus recorded, the data (1) and (3) recorded in the area A are reproduced, and this audio signal is reproduced. It is taken out to the output terminal 20. When the operation button 71B is pressed, the data (2) recorded in the area B is reproduced, and this audio signal is taken out to the output terminal 20.
[0017]
In this way, data recording / reproduction is performed for each of the divided areas A, B, C... On the mini-disc (MD) 12 corresponding to the plurality of operation buttons 71.
[0018]
Therefore, when a voice memo device is configured using such a mini-disc (MD), for example, by assigning the operation button 71 to each user, one mini-disc (MD) can be obtained with a simple configuration. ) Can be shared by multiple users.
[0019]
The so-called PIN number is set in combination with the above-described number buttons 0 to 9 to determine whether the PIN numbers match at the time of recording or playback, and recording or playback is performed only when they match. You can also. As a result, confidentiality among users can be maintained.
[0020]
The appearance of this apparatus is as shown in FIG. 3, for example. That is, in the figure, reference numeral 21 denotes a disk drive device to which a mini disk (MD) 12 is mounted. Reference numeral 22 denotes a microphone connected to the input terminal 1, and reference numeral 23 denotes a speaker connected to the output terminal 20. Below these, a plurality of operation buttons 71 constituting the operation unit 7 described above, a numeric button 72 of 0 to 9 and a recording button 73 are provided.
[0021]
Thus, according to the above-described apparatus, the recording area of the disk 12 is divided into a plurality of areas, and the operation means (operation button 71) corresponding to each division is provided, so that the correspondence with each user is very easy. It can be taken.
[0022]
In the above-described apparatus, the number of divided areas can be arbitrarily set as necessary. Further, in such a case, display of whether or not the operation button 71 can be used may be performed according to the number of divisions set.
[0023]
Further, in the above-described apparatus, when N access points are provided on the disc, the name of this access point is set to 0 to N-1, and normally only the access points 1 to N-1 are recorded and reproduced. In addition, it can be applied to a case where a zero access point can be recorded / reproduced by a predetermined operation, and a specific message or the like is recorded / reproduced to / from this 0 access point.
[0024]
