Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc recording / reproducing apparatus capable of reading label information of a recordable / reproducible disc such as a mini disc and displaying the label information.

[0002]

2. Description of the Related Art There are known two types of mini-disc MD having a diameter smaller than that of a compact disc CD, a read-only disc and a recordable / reproducible disc.

FIG. 4 is a schematic system diagram of a main part of a disk recording / reproducing apparatus 10 which can also use a recordable / reproducible mini disk (hereinafter simply referred to as a disk). The surface 11a of the recording / reproducing disk 11 is shown in FIG. A data recording system 12 is arranged in confrontation with the above.

If a magneto-optical disk is taken as an example of the disk 11, the recording system 12 has an encoder 14 and a recording head 15. For example, a music signal supplied to a terminal 13 is digitized by the encoder 14 and an error occurs. After various kinds of signal processing such as correction processing and data compression processing necessary for recording on the mini disk are performed, data relating to this music signal is supplied to the recording head 15 and magnetic domains corresponding to the music data are formed on the disk 11. Then, the music data is recorded.

A data reproducing system 16 is arranged on the back surface 11b side of the disk 11. Laser light is emitted from the optical pickup device 18 to the disk surface through the objective lens 17, and the reflected laser light is received by the optical pickup device 18 to receive the magnetic Kerr effect, and the recorded data is reproduced.

The recording data read by the optical pickup device 18 is subjected to data expansion processing in a decoder 19,
After data restoration processing such as error correction processing is performed, demodulation is performed and a music signal is output from the terminal 20.

Since the recording / reproducing process of the data is performed in the state where the disc 11 is loaded in the device main body 22 as shown in FIG. 5, the disc 11 is first loaded into the device main body 22 as shown in FIG. The recording system 12 is arranged on the upper surface side of the and the reproducing system 16 is arranged on the lower surface side.

DISCLOSURE OF THE INVENTION Disc 1
As shown in FIG. 6, on the front surface 11a side or the back surface 11b side of the No. 1, a label of a predetermined size in which all the information regarding the music signal such as the recording time, the performer, etc. is recorded, including the title of the music signal recorded on the disk 11. 27 is attached.

It may be desired to know the label information even when the disc is in use. However, in the case of a read-only disc, in the case of a recording / reproducing disc, the recording system 12 is arranged on both sides of the disc 11, particularly on the upper surface side, in the main body 22 of the apparatus, and therefore, as shown in FIGS. Even if a window 23 is formed on the upper surface of the main body 22 at a position facing the label on the surface 11a of the disk 11, the mechanism of the recording system 12 interferes with the window 23 and the contents of the label 27 cannot be seen. .

The same is true when the apparatus main body 22 for loading the disk 11 in the vertical direction is used instead of loading the disk 11 in the horizontal direction and the insertion opening 25 is provided at a position as shown in FIG.

Therefore, according to the present invention, even with such a recording / reproducing disc, the label information attached to the disc can be known even while the disc is in use.

[0012]

In order to solve the above-mentioned problems, according to the present invention, a read-only means for reading label information attached to the surface of a read-only or recordable / reproducible disc is arranged in the main body of the apparatus and read. The displayed label information is displayed on the display means.

[0013]

As shown in FIG. 1, the line sensor 30 in this example, which is the label information reading means, faces the surface (usually the surface 11a) of the loaded disk 11 to which the label 27 is attached. The line sensor 30 is provided to read label information when the disc is loaded.

The read label information is displayed on a two-dimensional display section 40 such as a liquid crystal provided on the upper surface of the apparatus main body 22. With this configuration, it is possible to know the label information of the used disc even when the disc is being used.
You can easily tell if you are using a playback-only disc.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a case where an example of a disk recording / reproducing apparatus according to the present invention is applied to a mini disk will be described in detail with reference to the drawings.

In the present invention, as shown in FIG. 1, the label 2 of the disk 11 (whether it is a recordable disk or a read-only disk) loaded in the apparatus main body 22 is used.
Label information reading means 30 is arranged so as to face the surface side (usually the surface 11a side) to which 7 is attached.

In this example, the reading means 3 is a line sensor.
0 is configured, and the line sensor 30 selected to have a length that can cover the label 27 attached to the disc 11 in the lateral direction in a position close to the disc insertion port 25 is parallel to the insertion port 25 and after loading. It is arranged at a predetermined distance from the disk 11.

On the upper surface side of the apparatus main body 22, as shown in FIG. 1, there is provided a display section 40 used for displaying label information. The display unit 40 can use a two-dimensional display means such as a liquid crystal, and its size does not have to be the same as the size of the label attached to the disc as shown in the figure, The size is decided in consideration of balance and the like.

In addition to the label information, the display section 40 displays other information (additional information to the disc such as the state of the function mode of the device, the reproduction channel, the reproduction time, etc.) by switching or in a time division manner with the label information. It can also be displayed. That is, the dual-purpose configuration may be used.

FIG. 2 shows a specific example of the label information display device. The label information (image information) attached to the disc 11 is read line by line by the line sensor 30, and the read label information (image signal) is read by the amplifier 3.
It is supplied to the signal processing means 32 via 1 and converted into a signal form suitable for display, and then supplied to the display section 40 as its drive signal. The drive signal may be a binary signal, a multi-valued signal, a monochrome signal or a color signal.

As a result, since the read label information is displayed on the display section 40, the user can easily know what kind of disc is currently loaded and used.

The display section 40 may be constructed separately from the apparatus main body 22 as shown in FIG. By doing so, the display area of the display unit 40 can be increased to some extent, and accordingly, label display with good resolution can be realized. In the case of the display unit 40 having the configuration of FIG. 3, the display unit 40 is configured to be detachable from the device body 22.

[0023]

As described above, in the disk recording / reproducing apparatus according to the present invention, the information of the label attached to the disk loaded in the apparatus body is read and displayed on the display section. is there.

According to this, since the label information attached to the disc can be seen even after the disc is loaded, it is possible to know the label information of the disc used even when the disc is in use. The effect is that you can easily see if you are using a different disk. Of course, this configuration has the effect of displaying the disc information regardless of whether the disc used is a recording / reproducing disc or a reproducing-only disc.

Therefore, the present invention is extremely suitable when applied to a disc recording / reproducing apparatus such as a mini disc capable of reproducing any type of disc.
