DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance board for an optical disk drive for removing dust adhering to an optical head.

[0002]

2. Description of the Related Art An optical disk or a magneto-optical disk is used to record sound information, image information, computer data and programs, and the disk is set on a playback device or a playback / recording device and rotated. It is designed to receive the reflected light of the irradiated light. Since the surface of the lens body of the optical head is exposed in the internal space of the disk device, dust easily adheres to the surface and is likely to adversely affect information recording or reproduction.

[0003] For this reason, conventionally, a brush has been proposed which cleans the surface of an optical head by implanting a brush on a disk having substantially the same shape as a disk disk and rotating the base.
Since such a panel can record a signal, for example, a check signal can be recorded in order to check the performance of each device such as an amplifier and a speaker of an AV device or the like, and the maintenance function can be enhanced. There are various check signals for adjusting the output balance between the left and right, and for checking the frequency characteristics. It is also conceivable to play beautiful audio signals and add value to the panel other than the maintenance function.

As described above, adding a check signal reproducing function and an audio signal reproducing function other than the lens cleaning function of the disk device to the disk body can increase the commercial value. However, a brush or the like may be provided on a part of the disk body. When the lens cleaning member is implanted, the cleaning member may cause noise, and the carefully recorded check signal or audio signal may not be reproduced normally. In addition, the recording surface of a reproduced signal such as a check signal must be properly cleaned with a cleaning cloth or the like. However, this also has a disadvantage that the implanted cleaning member interferes and cannot be sufficiently performed.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned disadvantages.

[0006]

SUMMARY OF THE INVENTION The invention of the present invention
In a maintenance board of an optical disk device having a cleaning area D for cleaning the lens 21 of the optical head 20 and a reproduction signal recording area C, the reproduction signal recording area C is provided as a separate track on the outer peripheral side of the cleaning area D. It was arranged.

[0007]

In this configuration, since the cleaning member existing in the cleaning area D is arranged at a position different from the reproduction signal recording area C, the cleaning member does not hinder the reproduction of the recorded signal. Absent. Since the reproduction signal recording area C is independent on another track, this area C
Only the use can be easily operated. Further, during the reproduction operation of the outer reproduction signal recording area C, the lens automatically passes while hitting the cleaning member implanted in the cleaning area D located on the inner side. Done, convenient.
Further, although the cleaning of the disk surface is required for the reproduction signal recording area C, the cleaning member is not obstructed when the disk surface is wiped with a cleaning cloth or the like because the cleaning region is on the inner peripheral side.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a board 10 according to the present invention,
It has substantially the same shape as mCD. A TOC (Table of Contents) area A, a start greeting text recording area B, a cleaning area D in which a flocked body 22 as a cleaning member is implanted, and a check signal as a reproduction signal are recorded on the disk body 10 from the inner peripheral side. The check signal recording area C and the end greeting sentence recording area E are provided independently for each track. Each of the areas B, D, C, and E corresponds to a track selection operation of the disk device 30, and specifically, corresponds to the music selection buttons 1, 2, 3, and 4 of the disk device 30. In the TOC area A, a signal for listing the contents of the disk 10 is recorded on the disk device 30 shown in FIG.
The optical head 20 within 0 starts reading from this TOC area A. As the disk device 30, a laser disk, a device having both of them having a reproducing function, and the like can be considered in addition to the CD player.

After reading the TOC area A, the optical head 20 moves to the greeting recording area B which is the first track,
A message that informs the user of how to handle the board 10 is reproduced.

[0010] Specifically, "Thank you for purchasing XX. This time, pressing the music selection button 3 will clean the optical head of the disc playback device used by the customer. Cleaning is completed. Then, a check signal that can check the AV equipment used by the customer will be played back. Please use it to check the cleaning effect etc. "and the message is played back to the user The correspondence between the music selection button 31 in the disk device 30 and the function of the board 10 is notified.

Here, if the user does not operate the music selection button 31, the operation automatically shifts to the second track. The cleaning area D, which is the second track, has a sound area D1 and a silent area D2 on which a message indicating that cleaning is started is recorded.
A flocked body 22 having a width of about 0.6 mm, a length of about 8 mm and a height of about 8 mm is planted on a track on which a silent section signal is recorded, with the radiation direction as a longitudinal direction. Abuts on the surface of the lens 21. (FIG. 3
Since the lens cleaning by the operation of jumping over the second track is desirable, in order to prevent the user from accidentally continuing to reproduce the second track, the sounding portion D1 on the inner peripheral side of the cleaning area D is cleaned. Therefore, a message to skip is recorded. The user opens this message and is prompted to select the music selection button 3 again.

Software is recorded in the reproduction signal recording area C serving as the third track in order to add value. More specifically, a system check signal for determining whether or not the system is properly connected, a signal for performing a high-frequency and low-frequency reproduction limit check, and the like are recorded. Finally, a message indicating that the reproduction of the check signal has been completed is reproduced. The reproduced signal recorded here may be not only a signal for checking but also a music signal.

By selecting the music selection button 3, the reproduction signal recorded on the reproduction signal recording area C, which is the third track, is jumped over the cleaning area D and reproduced.
If left as it is, the end greeting recorded in the end greeting sentence recording area E as the next track is reproduced. When the optical head 20 jumps over the cleaning area D, the lens 21 moves in the radial direction while contacting the flocked body 22 rotating at a high speed, and the lens cleaning is completed.

Note that the lens 21 and the flocked body 22 are in contact with each other without performing the operation of jumping over the cleaning area D, and the cleaning is performed. In this case, the optical head 20
Follows the silent portion D2 of the cleaning area D successively, so that the cleaning time is longer than that in the case of the jumping, so that the lens may be damaged.

When a user uses the maintenance panel 10 of the optical disk device having the above configuration,
First, the board 10 is set on the disk device 30. Board 1
0 is set, and if the user does nothing, the TO
The start greeting text recording area B of the first track is first reproduced by the signal recorded in the C area A. The user selects the music selection button 31 of the disk device 30 according to the reproduction content.
Select If left as it is, cleaning for a long time is started in the cleaning area D of the second track, but a message to skip the second track, such as "press the music selection button 3", is recorded in the first track. Long-term cleaning is avoided. In addition, since the skip prompt message is recorded in the sounded portion D1 also in the second track, the user can avoid cleaning for a long time even if the user continuously reproduces by mistake.

In the selected third track, a check sound or the like is reproduced, and the user can perform a system check, a capability check, and the like of the AV equipment used.

The operation of each of the other music selection buttons is as shown in FIG. As shown in the above embodiment, in the present invention, since the reproduction signal recording area C is provided as a separate track on the outer peripheral side of the cleaning area D, the cleaning effect by the flocked body 22 is continuously and immediately performed. It can be confirmed by the reproduction of the file.

In addition, the cleaning of the board surface of the check signal recording area is simplified since there is no obstruction member such as the flocked body 22 on the outer periphery. In this embodiment, the check signal always passes through the cleaning area when the check signal is reproduced, so that the cleaning function is linked with the reproduction operation. (See Fig. 4)

In the above embodiment, a CD has been mainly described. However, as an optical disk, there are a laser disk, a magneto-optical disk and the like in addition to a CD, and not only for music and video but also for computer data and program recording. Including. As a cleaning body for the optical head, a method of generating a flow velocity of air other than the above-described flocked body and blowing off dust by wind pressure is also conceivable.

[0020]

As described above, according to the present invention,
In a maintenance board of an optical disk device having a cleaning area D in which a cleaning member for cleaning the lens 21 of the optical head 20 is implanted and a reproduction signal recording area C, the reproduction area is provided on the outer peripheral side of the cleaning area D. Since the signal recording area C is provided as a separate track, a. Since the cleaning is performed by the track number instruction to the reproduction signal recording area, the lens comes into contact with the cleaning member implanted in the cleaning area while performing a seek operation, so that the contact time between the lens and the cleaning member becomes appropriate, and the lens is not damaged. Cleaning can be performed well. b. Since there is a reproduction recording area in which high value-added information is recorded on the outer peripheral side of the cleaning area, if the user performs a reproduction operation with a feeling of operation, the cleaning is completed, and the merchantability is improved. c. Since the recorded information is automatically reproduced with the lens in the best condition, the reproducibility of the reproduced information is improved, and the reliability of the check signal etc. is increased.
Further, even for ordinary music, the reproduction quality is improved, and the cleaning effect of the lens cleaner can be immediately confirmed. d. Since the cleaning member is located on the inner peripheral side when cleaning the reproduction signal recording surface, it does not hinder the wiping operation. It has the function and effect described above.
