Press the music selection button 4 to start
If the third track is skipped, the lens
The lens has already been cleaned when moving to track 4
The area has passed and cleaning has been completed. You
In other words, the greeting recording area of the first track is
It also functions as a commanding area for starting the tuning. If the music selection button 31 is not operated, the control automatically moves to the second track and the check signal reproducing function operates, and then the cleaning function of the lens 21 of the optical head 20 on the third track operates.

In the check signal recording area C serving as the second track, specifically, a system check signal capable of judging whether or not the system is correctly connected, a wide-range and low-frequency reproduction limit check, and the like can be performed. Signals and the like are recorded. Finally, a message indicating that the reproduction of the check signal has been completed is reproduced.

A cleaning area D as a third track includes a cleaning start command area D1 in which a message indicating that cleaning is started is recorded, and a cleaning execution area D3 in which a flocked body 22 such as a brush as cleaning means is provided upright. And anti-hair loss areas D2 and D4 on both sides of the cleaning execution area D3. In the cleaning start command area D1, a command message such as "Press the music selection button 4 to perform cleaning" is recorded. Also, in the cleaning execution area D3, an abnormal sound such as a beeping sound or a “tune selection button ○”
Press or stop button to stop cleaning immediately. , Etc., is recorded as a warning message indicating that cleaning should be immediately stopped.

In the cleaning execution area D3, the disk 10
0.6 mm wide and 8 mm long with the radiation direction of the longitudinal direction
A flocked body 22 such as a brush having a height of about 8 mm is planted in the recess 23 having a height of about 8 mm, and the tip of the flocked body 22 comes into contact with the surface of the lens 21 (see FIG. 3). The anti-hair fall areas D2 and D4 are safety areas secured so that reading of the pickup head 20 in both areas D1 and E will not be adversely affected even if the flocked body 22 falls down sideways. By the way, dirt such as smoke from cigarettes and the like is easily and strongly attached to the optical head 20, and such dirt cannot be removed by a simple linear brush. Therefore, as shown in FIG. 4, it is desirable that the brush is provided with liquid impregnating property without forming fine irregularities on the surface and impregnated with a cleaning liquid such as isopropyl alcohol liquid. According to such a brush 22, the cleaning liquid dissolves and removes the strongly adhered dirt such as the above, and further, the dirt can be scraped off by the unevenness of the surface. As a means for imparting liquid-containing property to the brush, for example, it may be a porous shape, and of course, various shapes of unevenness can be considered.

When the message in the cleaning start command area D1 is confirmed and the music selection button 4 is pressed, the end greeting sentence recorded in the end greeting sentence recording area E, which is the fourth track, jumps over the cleaning area D and is reproduced. . When the optical head 20 jumps over the cleaning area D, the lens 21 skips in the radial direction while abutting on the flocked body 22 rotating at high speed, and the lens cleaning is completed.

As described above, the optical head 20 skips in the radial direction from the cleaning start command area D1 to the end greeting message recording area E, whereby the lens 21 is instantaneously cleaned, and the excessive cleaning of the lens 21 is performed. Be avoided.
