  • Patent number: 6587289
    Abstract: A magnetic transfer method for magnetically transferring information signals such as servo signals from a master medium to a slave medium, capable of reducing a range of signal missing due to insufficient contact of the two mediums originating from an adhering substance, thus enhancing signal quality. When the master medium bearing an information signal and the slave medium are brought into close contact with each other, a transferring magnetic field is applied thereto, thus magnetically transferring the information signal from the master medium to the slave medium. An elastic member made of a material having an elastic property so as to deform in accordance with a surface shape of the slave medium during contact pressure application and to restore to an original surface shape thereof during release of the slave medium from the master medium can be interposed between a back of the slave medium and a pressing surface of a pressing support member.

  • Publication number: 20020159177
    Abstract: When a master medium and a slave medium are brought into close contact and a transfer magnetic field is applied thereto to perform magnetic transfer, the leakage magnetic field intensity of the transfer magnetic field is regulated to within a permissible range, making possible the transfer of an exact magnetic pattern. After a magnetic field is applied to the slave face in the track direction thereof to initially magnetize the slave medium in the track direction, the master medium and the slave medium are brought into close contact. When applying a transfer magnetic field in the track direction of the slave face to perform a magnetic transfer, the magnetic field intensity component in the direction opposite that in which the transfer magnetic field is to be applied is regulated to less than or equal to ½ the magnetic coercive force Hcs of the slave medium over the entire slave surface.

  • Patent number: 5073708
    Abstract: An apparatus for inspecting vessels for the presence of foreign matters inspects the vessel as it undergoes a reverse rotation which follows a forward rotation. A receptacle on which the vessel is driven for rotation is mounted on a rotatable body, and a receptacle is driven by a control motor for rotation in the forward and the reverse direction. A controller which controls the control motor detects any change in the speed of rotation of the rotatable body, and responds to such change by controlling the motor so that a given, predetermined permissible inspecting condition of the vessel is maintained during its forward and reverse rotation in the presence of a change in the speed of rotation of the rotatable body.
