Title: Optical disk
Inventor: KIRINO FUMIYOSHI
IPC: G11B11/105
Filed: 1993-05-12
Abstract: PURPOSE:To enable ultra-high-density recording and to improve rewriting characteristics by covering the optical disk with a required resin layer to control the quantity of the heat entering and going out of a recording film. CONSTITUTION:A silicon nitride film 2, the magneto-optical recording film 3 consisting of TbFeCoNb, a silicon nitride film 4 and a metallic film 5 consisting of Al96Ti4 metallic film 5 are laminated on a substrate 1 to form the optical disk. The surface of the optical disk is coated with the resin layer 6 controlled in thermal conductivity to suppress the flow of the heat in the direction parallel with the substrate 1, to increase the flow of the heat in the direction perpendicular to the substrate 1, to control the quantity of the heat inputted and outputted from and to the film 3 and to execute recording/ reproducing/erasing with specified patterns. As a result, the thermal interference between recording bits and between tracks is drastically suppressed and microrecording domains are densely formed. The recording at the ultra-high density is thus possible. Since the temp. of the film 3 does not rise at the time of recording, the rewriting characteristics of the repeating characteristics of recording/erasing are enhanced.

Filed: 1992-04-03
Abstract: PURPOSE:To improve running stability and comfortableness to ride by selectively outputting a signal of sensor piezoelectric element from a controller by vibrating a senor weight, and vibrating an actuator weight by an actuator piezoelectric element. CONSTITUTION:At the time of vibrating a piston rod 2, a signal is output to a controller C from a sensor piezoelectric element 21 by vibrating a sensor weight 22, and in the controller C, a command signal is not output to an actuator piezoelectric element 23, when a vibration frequency is in above/under spring resonance regions, but output to the piezoelectric element 23 when the vibration frequency is beyond the above spring resonance region and in the under spring resonance region. Since the piezoelectric element 23 is expanded by electrification and contracted by release therefrom, when the command signal from the controller C is an on-off signal for a short time, expansion and contraction of the piezoelectric element 23 are repeated in a short time, to vibrate an actuator weight 24. When the actuator weight 24 is set reverse to the vibration of the piston rod 2, the vibration can be suppressed.
