F.-ly, 3 ill.

The invention relates to recording devices and/or reproduction of information with mutual relative movement of the optical storage medium and the optical head and can be used in the information technology, such as devices, digital audio, digital video recording devices, optical external storage devices of computers.

Known optical storage medium made as transparent to laser radiation of a cylindrical substrate on the inner surface which caused the recording medium, and is enclosed in a stationary air-tight container, the inner cavity of which is filled with the immersion liquid, and the end sections of the cylindrical substrate is fixed to the rotor and the armature displacement is fixed container, in the side wall of which there is transparent to laser radiation [1] .

The disadvantage of analog is low accuracy and reliability of playback and recording information due to the fact that in the spectrum of axial and radial beating the optical media can be poorly working on relevant systems of automatic control (autotraining and AF) large magnitude higher harmonics due to inaccuracy of manufacture of the electric rotating optical media.

The closest in technical essence and the maximum number of matching distinguishing characteristics is the media, made as transparent to laser radiation of a cylindrical substrate on the inner surface which caused the recording medium, and enclosed in a still air-tight container, an internal cavity which can be filled with the immersion liquid, and at least one of the end sections of the cylindrical substrate is fixed to the rotor of the electric drive rotation, the stator of which is placed on the outer surface of the container, the side wall of which has a transparent shall be playback and recording information, what in the spectrum of axial and radial beating the optical media can be poorly working on relevant systems of automatic control (autotraining and AF) large magnitude higher harmonics due to inaccuracy of manufacture of the actuator rotation and axial movement and inaccurate placement of their stators on the outer surface of the container.

The aim of the invention is to improve the accuracy and reliability of recording and reproduction of information by suppressing higher harmonics of wobbling of the recording media.

The objective is achieved by the fact that in media containing made in the form of bodies of rotation of the substrate surface which caused the recording medium, and the rotor of the electric rotating entered is placed between the substrate and the rotor damper.

The objective is achieved by the fact that the media put a damper disposed between the substrate, is made tubular, and anchor drive axial movement, the stator of which is placed on the outer surface of the fixed container, comprising a substrate with a recording medium and filled with the immersion medium, and brigetta, the dampers are made in the form of bodies of revolution.

In Fig. 1 shows an embodiment of the inventive device with reference to the disk optical storage medium of Fig. 2 is an embodiment of the inventive device with respect to the cylindrical optical storage medium of Fig. 3 is another embodiment of the inventive device with respect to the cylindrical optical media.

The optical information carrier shown in Fig. 1, contains two transparent to laser radiation (for example, glass, quartz, acrylic glass) substrates 1 and 2 having the form of a disk and placed against each other. On the surface of the substrate, facing each other, caused to the recording medium 3 and 4 (for example, chalcogenide, metal, ORGANOMETALLIC), respectively. Both substrates through a toroidal damper 5 (for example, of rubber, plastics, leather) coupled to the rotor 6 of the electric drive rotation (e.g., synchronous, stepper, asynchronous), the stator 7 which is located under the disk media. The centering of the rotor 6 of the electric drive rotation relative to the stator 7 is provided aerostatic bearing, the drawing for simplicity not polerowanie laser light to the recording medium 3 (or after perevertilenko described disk media to the environment 4) is fed to the movable optical head 9 (in the drawing shown symbolically by the lens), optical storage media not included and shown only for convenience of explanation of his work.

The media depicted in Fig. 2, contains transparent to laser radiation substrate 10 (for example, glass, quartz, plastics), on the internal surface of which caused the recording medium 11 (for example, ORGANOMETALLIC, metal chalcogenide). To the end face of the substrate 10 through the circular damper 12 from a material with a large coefficient of dissipation (e.g., rubber, plastic) attached to the rotor 13 of the electric drive rotation (e.g., stepper, synchronous, asynchronous). The substrate 10 mounted on it with a damper 12 and the rotor 13 is enclosed in a stationary pressurized container 14, having in its side wall transparent to laser radiation window 15 through which the recording medium 11 is fed focused movable head 16 (media not included) laser radiation. In the end part of the side surface of stationary pressurized container 14 placed the stator 17 of actuator rotation.

The media depicted in Fig. 3, contains transparent to laser radiation tubular substrate 18 (e.g., from Karenina, ORGANOMETALLIC, metal). On the mechanical parts of the substrate 18 through the toroidal dampers 20, 21 (for example, of rubber, plastics) fixed toroidal rotor 22 of the electric rotation and anchor 23 of the actuator axial movement. The dampers 20, 21, the rotor 22 and the anchor 23 is fixed sealing the internal cavity of the carrier trubka insert 24 (for example, from the same material as the substrate 18). Such cylindrical information carrier is enclosed in an airtight container 25 (for example, duralumin), the inner cavity of which is filled with immersion liquid medium 26 (polymethylsiloxane, ethanol, Vodopyanova mixture) or gaseous (e.g., as proposed in the ed. St. USSR N 1427248). On the mechanical parts of the container 25 is placed stators 27 and 28 respectively of the actuator rotation and axial movement. In the middle part of the side surface of the container 25 has transparent to laser radiation window 29 on which hosts immersion lens 30 (shown symbolically in the drawing lens).

There may be other implementations of the inventive media, different design of main components, materials used, otherwise the principle of recording and vosproizveden follows (see Fig. 1).

When recording or reproduction of information by the actuator includes a rotor 6 and a stator 7, the substrates 1, 2 coated recording media 3, 4 are rotated. At the same time the radial movement of the movable optical head 9 of the focused laser radiation is displayed on a given information track and writes to or reads data from it. When this damper 5 are smoothed out the jerks of the rotor 6 due to inaccuracy of manufacture, the inaccuracy of mutual spatial position and other factors, which provides more accurate and reliable operation of autotracing and AF (in the drawing for simplicity not shown) and, ultimately, improving the accuracy and reliability of recording and reproduction of information.

The inventive information carrier shown in Fig. 2, operates as follows.

When recording and reproduction of information by the actuator includes a rotor 13 and a stator 17, the substrate 10 with the recording medium 11 is driven. At the same time the head 16 of the focused laser radiation is displayed on a given information track, which is read or to which zapisi the ROM 12, whereby movement of the substrate 10 becomes more ordered. This facilitates the operation of autotracing and AF and accordingly increases the accuracy and reliability of recording and reproduction of information.

The media depicted in Fig. 3, operates as follows.

When recording and reproduction of information of the substrate 18 with the recording medium 19 is rotated and is moved sufficiently in the axial direction under the influence of the actuator rotation containing the rotor 22 and the stator 27 and axial movement, containing the anchor 23 and the stator 28. Arising under the influence of the rotor 22 and the armature 23 with the stators 27 and 28 due to imperfections in the fabrication and placement of the actuators, and other factors jerks dampers 20, 21 and smoothed movement of the substrate 18 with the recording medium 19 therefore become more ordered. This facilitates the operation of autotracing and AF (in the drawing for simplicity not shown) and, therefore, increase the accuracy and reliability of recording and reproduction of information. Recording and reading of information on such media are provided with focused laser radiation through the immersion of the object 30 oby="ptx2">
