Title: Optical disk, and optical data memory system
Inventor: ROSEN HAL JERVIS
IPC: G11B7/24
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide an optical data memory system which uses an optical medium having plural recording layers. SOLUTION: The substrate supports recording stacks 90, 92 of plural layers which are spatially separated, and the stacks contain recording layers 53, 64 comprising reversible or rewritable phase transition material in an active state. The recording stack 90 nearest to the substrate where laser light irradiates the surface 49 contains a reverse-writing type reversible phase transition material, namely a phase transition material which having an amorphous initiating phase in which recording is done by heating with a laser beam to change the data region into a crystalline phase. The first recording layer 53 is in contact with dielectric layers 51, 55. These dielectric layers have a higher refractive index than that of the adjacent recording layer and act as optical interference thin film so that these layers give an optical interference effect to enhance the light in the recording stack. These optical interference thin films do not absorb light so that the laser light can be focused on the recording layer in the recording stack 92.

IPC: B23D25/12
Filed: 1979-09-28
Abstract: PURPOSE: To feed positively and smoothly a band steel to a blade part of a rotary durm or a succeeding step so as to improve the production efficiency of the shear by increasing the rigidity of the band steel to be fed to the rotary drum.  
     CONSTITUTION: A pair of feeding rollers 20, 21 are provided on the feeding side of the rotary drum of the shear instead of a pair of guide rollers conventionally used. One roller 20 is formed with a convex crown whereas the other roller 21 is formed with a concave crown opposing to the convex crown. The lower roller 21 rotates to transfer the band steel 6 as griped between the both rollers 20, 21. In this instance, the band steel 6 is curved in the width direction by pressing between the convex and concave crowns of the rollers 20, 21. Thus curved steel has an increased rigidity, which enables a positive and smooth feeding of the band steel and hence enhances the production efficiency of the shear.
