The basis of this utility model is the solution to the problem of increasing the device for cleaning optical heads for reading DVD CDs. According to a utility model, this goal is achieved due to the fact that in a device for cleaning optical heads for reading information from DVD CDs, including a cleaning CD, equipped with one or more cleaning bodies, having an internal, zero track containing input information about the DVD a CD, a track located under the cleaning element, and a track with a recording program for controlling the movement of optical heads for reading information from DVD CDs during the cleaning process, while a track with recording a control program I by the movement of the optical heads for reading information from DVD CDs during the cleaning process is located between the inner, zero, track and the track located under the cleaning body.

Description

The utility model relates to the field of storage of information on DVD CDs and can be used to clean optical heads, which are used to read information, mainly from DVD 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 G 11 B 3/58, 12/16/1988.

The disadvantage of this device is the low cleaning efficiency of the optical heads and lack of functionality. Also known is a device for cleaning optical heads for reading information from compact discs, comprising a compact disc having a cleaning organ 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 G 11 B 7/00, 04.10.1993.

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

A device for cleaning optical heads for reading information from various types of compact discs, including video CDs (DVD). The device comprises a cleaning CD equipped with one or more cleaning bodies, having an internal zero track containing input information about the video CD, a track located under the cleaning element, and an additional track with the recording of the motion control program of the optical heads for reading information from the video compact disks during cleaning, RU 34796 U1.

This device, taken as a prototype of this utility model, is quite effective in cleaning optical heads used to read information from audio and computer CDs, but it does not provide the necessary degree of cleaning for optical heads intended for video (DVD) CDs.

This is because the video CD is read from the center to the periphery. Therefore, when using the known device, the track located under the cleaning organ (usually containing the test) is first read, and only then the track is read with the recording of the optical head motion control program. As a result, the track located under the cleaning element is read at the minimum speed and, accordingly, at the same speed, the head contacts the cleaning organ, which significantly reduces the cleaning efficiency.

The basis of this utility model is the solution to the problem of increasing the efficiency of a device for cleaning optical heads for reading information from video (DVD) CDs.

According to a utility model, this goal is achieved due to the fact that in a device for cleaning optical heads for reading information from DVD CDs, including a cleaning CD, equipped with one or more cleaning bodies, having an internal, zero track containing input information about the DVD CD

the track located under the cleaning element, and the track with the recording of the program for controlling the optical heads of reading information from DVD CDs during the cleaning process, the track with the recording of the program for controlling the optical heads of reading information from DVD CDs during the cleaning process is located between the internal, zero , a track and a track located under the cleaning organ.

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 cleaning CD 1. Information is provided on the disk to ensure its loading, rotation, and a number of additional functions when it is installed in a DVD player. The CD 1 in a particular example contains one cleaning organ 2. Several cleaning organs may be present.

On the internal track zero 3 (standard DVD) information about the type of disc (“DVD disc”) is placed and service commands for the playback device (DVD player) are encoded.

Directly below element 2, which is an elongated brush made of soft synthetic fibers, in a specific example, track 4 is located. This can be a video-audio test recording

or the so-called “silence record”.

Track 5 with recording a motion control program for optical heads for reading information from DVD CDs during the cleaning process is located between tracks 3 and 4.

This program allows the user to control the movement of the optical head of a DVD player, for example, using the remote control, as well as control the cleaning process and its quality, the program is recorded in the format of the main menu of DVD CDs.

The device operates as follows:

If disc 1 is inserted in the DVD player, then information is automatically read from track 3, and disc 1 is recognized as a DVD CD. Then, information is read from track 5 with the recording of the optical head motion control program in the format of the main menu of the DVD CD. It is possible to display this menu on a TV or monitor. Using the remote control, the user selects the desired operations from the menu. If the cleaning operation is selected, then the path 4 is accessed and dirt is removed from the optical head; At the same time, an audio-video test can be played.

A device for cleaning optical heads for reading information from DVD discs is manufactured in the factory using conventional equipment and known materials, which

determines, according to the applicant, his compliance with the criterion of "industrial applicability".

Claims (1)

A device for cleaning optical heads for reading information from DVD CDs, including a cleaning CD, provided with one or more cleaning bodies, having an inner, zero, track containing introductory information about the DVD CD, a track located under the cleaning element, and a track with recording a program for controlling the movement of optical heads for reading information from DVD CDs during the cleaning process, characterized in that a track with a recording program for controlling the movement of optical heads for reading optical information from a DVD and a DVD CD in the cleaning process is disposed between the internal zero track and the track beneath the cleaner body.
