    摘要： An information recording apparatus including a device for driving an optical-disk's master disk, an electron lens barrel for having an electron beam irradiate a recording surface of a disk, a translational device for producing, between the disk and the electron lens barrel, a relative movement in a direction parallel to the recording surface and a container for enclosing the elements of the apparatus adapted to support a vacuum atmosphere. The driving device includes a turn table 4, a spindle 14a for supporting the turn table, a motor 14 for driving the spindle, and a magnetic shield for preventing magnetic fields of the motor from leaking outward. The motor is enclosed in the shield to prevent its magnetic fields from affecting the electron beam, which makes it possible to record information with high accuracy. The use of the motor as a drive source realizes easier and more responsive control of the turn table than that in the prior art.

    摘要： A mold is provided, at an outer circumferential region thereof, with portions to be gripped, to allow a transfer apparatus to perform transferring to an object. The portions to be gripped are formed in a different shape from the remaining portion of the outer circumferential region. For a mold set including two molds, each of the molds is provided, at an outer circumferential region thereof, with portions to be gripped, to allow the transfer apparatus to perform transferring to the object.The portions to be gripped are formed in a different shape from the remaining portion of the outer circumferential region. The portions to be gripped of one of the molds and the portions to be gripped of the other mold are disposed at different angular positions.

    摘要： A master disk exposing apparatus having: a turntable for rotating a master disk; moving means for horizontally moving the turntable in at least one direction; beam irradiating means for irradiating an electron beam toward the turntable, thereby forming a beam spot onto the turntable or the master disk; beam deflecting means for deflecting the beam; and control means for controlling the moving means, the beam irradiating means, and the beam deflecting means, wherein the control means includes initializing means for executing an initial operation to drive at least either the moving means or the beam deflecting means and make an origin of the beam spot coincide with a rotational center of the turntable at the time of activation. An apparatus and a method for easily adjusting a deviation between an origin of an irradiating position of the recording beam and the rotational center of the turntable are, thus, provided.
