Title: Optical recording medium
Inventor: TAKAHASHI HIDEJI
IPC: G11B7/24085
Filed: 1990-05-28
Abstract: PURPOSE:To improve the S/N of a signal system and to facilitate the position detection of peaks as well as to lessen the generation of reading out errors by confining the depth of pits within a 1/8 to 3/8 range of the wavelength of coherent light forming interference patterns. CONSTITUTION:The primary interference light is subjected to the max. modulation when the depth of the pits is 1/4 the wavelength and exhibits sufficient intensity even near this wavelength. The pits of this optical recording medium are formed to the depth of 1/8 to 3/8 the wavelength of the laser beam for reproducing by using a recorder 10. The depth of the pits formed in such a manner is adjusted by regulating the output of a laser diode 12 and the irradiation time of the laser beam. Consequently, the S/N in a reproducing device 22 is kept always good and the peaks of the primary interference light are easily and exactly detected. The reading out errors are thus decreased.

Title: Composite type thin film magnetic head
Inventor: MARUYAMA TAKAO
IPC: G11B5/39
Filed: 1986-06-10
Abstract: PURPOSE:To attain the high efficiency for the reproducing state by using part of both a thin film inductive head and a sealed type MR head made individually in common and incorporating it without reducing the function of both the heads. CONSTITUTION:The MR element 5, yokes 2, 3 being two return paths leading magnetic flux to a face oppose to a medium through the upper and lower parts of the MR element 5 and coupled magnetically to the MR element 5 at the opposite side of the face opposed to the medium, and a coil 4 wound in spiral between the yokes 2, 3 are provided. The signal magnetic flux from the medium led by the yoke 7 passes through the MR element 5 at the reproduction and returns to the medium through the upper yoke 2 and the lower yoke 3. That is, the upper yoke 2 and the lower yoke 3 act like the return path of the signal magnetic field and the shield of the MR element 5. Since the MR element 5 detects the vertical magnetic field from the medium, high resolution is attained and since the return path is provided, a high efficiency is attained.

Abstract: PURPOSE:To measure precisely, in a nondestructive manner, the refractive index and the layer thickness of an intermediate layer held by two substances between, by measuring an S-polarization reflectance and a P-polarization reflectance for each angle of incidence of a monochromatic light of a wavelength from the clad layer side and by computing the refractive index and the layer thickness of the intermediate layer therefrom. CONSTITUTION:In a medium 10 of incidence having a known refractive index n0, a monochromatic light of a wavelength lambda is made to enter, in the form of S polarization and/or P polarization, at one or more angles of incidence from the side of a clad layer 12. An S-polarization reflectance Rs and/or a P-polarization reflectance Rp is measured for each angle of incidence. A value ¦r12s¦<2> and/or a value ¦r12p¦<2> is calculated by a computing equation and reckoned as the reflectance of the S polarization and/or the P polarization at the time when the monochromatic light of the wavelength lambda is made to enter an intermediate layer 13 directly in the medium 10 of incidence, and by using this reflectance, the refractive index and/or the layer thickness of the intermediate layer 13 is computed. Herein the values r12s' and r12p' are composite amplitude reflectances obtained from the reflection by the boundary face of the clad layer 12 and the intermediate layer 13 and the reflection by boundary face of the intermediate layer 13 and a substrate 14.

Filed: 1977-11-16
Abstract: PURPOSE: To make it possible to discriminate which a sector check error comes from troubles at a storage or at a controller by providing sector lock check means in the storage using a recording medium such as a disc.  
     CONSTITUTION: An FF 7, which is mounted in a rotary type storage, is reset by an index clock 10. Each time any selector clock is fed, the FF 7 is inverted, and an exclusive AND gate 13 compares the stable Q output and the signals read out from a data truck. As a result, the compared results of the gate 13 upon generation of check timing pulses are fed through a NAND gate 15 to an FF 16 so that the output of the FF 16 is inverted in accordance with the existence of asector error thereby to detect the error in the sector check. Thus, it is possible to eliminate the difficulty as to which the error is generated due to the trouble at the side of a turning device or the controller in case error detecting means is provided at the controller side. Moreover, it is also possible to simplify the construction of the controller.
