Description

OPTICAL CLEANING DEVICE

READING INFORMATION FROM CDS

The utility model relates to the field of storage of information on compact discs and can be used to clean optical heads, which are used to read information from various types of compact discs, including computer, and video CDs.

A device for cleaning optical heads for reading information from compact discs, comprising a compact disc with a point cleaning element; there are two control tracks on the CD that contain information that allows the disk to rotate and stop; the tracks are located in the center of the disk, see US 5088083, IPC G11B 3/58, 12/16/1988.

The disadvantage of this device is the low cleaning efficiency of the optical heads and lack of functionality.

It is also known a device for cleaning optical heads for reading information from compact discs, comprising a compact disc having a cleaning body made in the form of a combination of five point elements, each of which is a brush in the form of a hair bundle; these elements are arranged in a spiral. The disc contains a track with background information and an area with instructional information and background music, see US 5499228, IPC G11B 7/00, 04.10.1993.

This technical solution was made as a prototype of this utility model.

The disc is inserted into the computer’s CD-ROM or CD player, while the input information is read (disc name, service information). Then the device that drives the disk is turned on, and a voice instruction for using the disk is played. After that, the disk cleans the lenses from dusty contaminants using cleaning elements, after which it stops after a specified time.

The disadvantage of this technical solution is the lack of control and management of the cleaning process of the optical head, there is no possibility of testing audio systems, verifying the correct connection of speakers; in case of cleaning

optical heads of the computer’s CD-ROM is not possible to control the cleaning process using the mouse or keyboard.

The present utility model is based on solving the problem of expanding the functionality of a device for cleaning optical heads for reading information from CDs.

According to the utility model, this goal is achieved due to the fact that the device for cleaning optical heads for reading information from CDs contains a CD equipped with a cleaning organ containing introductory information about the CD on the inner zero track and on the next track sound instructive information about using the compact disc, the cleaning body is made in the form of a linear element, while the disc is equipped with an additional track with sound recording and a track with recording the optical motion control program eskih heads during cleaning, and the cleaning body is placed over the track with the audio recording.

The applicant has not identified technical solutions that are identical to the claimed utility model, which allows us to conclude that it meets the criterion of "novelty.

The drawing shows a General view of the claimed device. In a specific example, the device contains a 5-inch compact disk 1. Information is provided on the disk to ensure its loading, rotation and

A number of additional functions for installing it in a CD player or CD-ROM drive of a computer.

On the so-called zero track 1, (Red book standard), information about the disc name (“cleaning disc)” is placed, and service commands for the playback device are encoded.

On the next track 3 immediately after it, there is a voice instruction for using the disc (recording format is CD-DA, digital audio CD), on the surface of which a cleaning organ is fixed in the form of a linear element 4, which is an elongated brush made of soft synthetic fibers.

Directly below element 4 is a track 5 with sound recording, in particular with a stereo audio test. CD-DA recording format.

A program that allows the user to control the movement of the optical head of the device (for example, using a computer mouse), as well as to monitor the progress of the cleaning process and its quality, is recorded on track 6 in CD-ROM format (Yellow book standard).

The presence of tracks of two different standards on one disc makes it compatible and most effective when cleaning the optical heads of both CD players and CD-ROM drives of computers.

Sj

The device operates as follows:

If disc 1 is inserted in a CD player, then information is automatically read from track 2, and it is recognized as a regular music CD. Then there is an automatic playback of information from track 3 with voice instructions. In it, in particular, it is reported that for cleaning, you should play the track 5 located above element 4. When accessing this track, dirt is removed from the optical head and at the same time a stereo audio test is heard in the speaker system. If the duration in a specific example is 40 s, but the user decides that the sound is high enough, then he can remove the disk from the device ahead of time.

If disk 1 is inserted into the computer’s CD-ROM drive, it is recognized as a computer CD-ROM drive designed to work with all versions of Windows operating systems. After loading, the main menu of the cleaning disc appears on the display. By activating the corresponding display areas with the mouse, you can not only clean the optical system of the CD-ROM drive and listen to the audio test through the computer speaker system, but also check the data transfer speed from disk to computer (it depends on

degree of contamination of the optical system), as well as call up on the display or print on the printer detailed recommendations for the care of the CD-ROM drive.

A device for cleaning optical heads for reading information from CDs is manufactured in the factory using conventional equipment and known materials, which, according to the applicant, determines its compliance with the criterion of “industrial applicability.
