Title: Optical head cleaning device
Inventor: NAKADA AKIFUMI
IPC: G11B7/12
Filed: 1986-05-16
Abstract: PURPOSE:To easily remove foreign matter sticking on the surface of the front end of a stop lens which is inserted into an optical recording and reproducing device and provided to the front end of an optical head by including a rotary brush which is supported rotatably in contact with the stop lens. CONSTITUTION:When an optical head cleaning device is inserted into the optical recording and reproducing device from the opening 26 of its front panel 25, a door 30 is rotated and then the device is inserted under the guidance of a cartridge holder 27 until the case part 3 is restrained by the front panel 25. The diameter D of a rotary brush is larger than the height H of a case insertion part, so the rotary brush 4 contacts the front end of the stop lens 46 at the front end of the optical head. Further, the optical head 44 is as long as the axial length of the rotary brush 4 wherever it is in the conveyance direction, so the stop lens 4 and rotary brush 4 contact each other. A control circuit 15 operates with a switch 14 pressed to drive and rotate a motor 7 for a certain time and then the rotary brush 4 is rotated to remove automatically foreign matter sticking on the front end surface of the stop lens 46 contacting it.

Title: Magnetic recording and reproducing device
Inventor: KIMURA SHIYOUSUKE
IPC: G11B15/30
Filed: 1983-06-22
Abstract: PURPOSE:To reduce the power consumption of a magnetic recording/reproducing device and to improve the stability of the recording/reproducing function, by providing a unidirectional clutch to a speed reduction means to release the engagement between a reel motor and a reel turntable when the reel turntable is rotated in a fixed direction and its opposite direction. CONSTITUTION:A unidirectional clutch mechanism is set at a sun gear 26a part of a speed reduction mechanism. That is, a spiral wire 33 is wound at a lower edge part 26c of the gear 26a as well as the outer circumference of a boss part 32 of a substrate 15 with minute clamping power. In a normal tape driving mode, i.e., when a magnetic tape 2 is taken up by a reel motor of the take-up side, the speed reduction mechanism is actuated to reduce the speed of a reel turntable 19 of the take-up side. In a reverse driving mode, the turntable 19 is pulled by the tape 2 and turned counterclockwise. However the load and load variance due to a speed reduction gear is greatly reduced since the speed reduction mechanism has no actuation.

Title: Information recording medium
Inventor: SUZUKI KATSUMI
IPC: G11B7/243
Filed: 1988-05-12
Abstract: PURPOSE:To enable fast erasing and to contrive to record and erase in fast rotation by constituting a recording layer of TeAuN alloy having a specific composition. CONSTITUTION:A protective layer 12, recording layer 13, protective layer 14 and surface protective layer 15 are formed on a substrate 11 on which pregrooves are already provided. The recording layer 13 is constituted of Te100-xAux(x represents atomic%, 1<=x<=8) alloy to which N is added. As the crystallization rate of Te is high, a recording mark 19 in the recording layer 13 can be crystallized and erased fast by continuous irradiating with laser beam 18. Thus, recording and erasing can be performed even when the disk rotates fast, as well as the amorphous recording mark can be stabilized owing to rather high temp. of crystallization.
