Abstract: In one embodiment, a target alignment surface disposed on a target support mechanically engages a darkspace shield alignment surface disposed on a darkspace shield as the target is lodged into a chamber body. The respective alignment surfaces are shaped and positioned so that the darkspace shield is physically moved to a desired aligned position as the alignment surfaces engage each other. In this manner a darkspace shield may be directly aligned to a target within a semiconductor fabrication chamber to provide a suitable darkspace gap between the target and the darkspace shield.

Abstract: In an optical disc recording and reproducing apparatus, when a time shift determining unit determines that a time shift reproduction is currently performed, a reservation determining unit determines whether or not there is a timer reservation in the next place. When it is determined that there is the timer reservation and a pre-time determining unit determines that the timer reservation is performed a prescribed time before a reserved time, a first reservation performing unit performs an operation of a record by the timer reservation. Then, after the recording by the timer reservation is finished, a time shift reproducing unit continuously performs the time shift reproduction without turning off a power. After the time shift reproduction is continuously performed, when there is a timer reservation, a second reservation performing unit performs recording by the timer reservation.

Abstract: There is disclosed a disk drive having a magnetic device for applying a direct current magnetic field to the disk 1 by using a disk with a double-layered structure in which a soft magnetic layer is provided on a lower layer of the recording magnetic layer. The magnetic device generates a direct current magnetic field to uniform a magnetic domain state of the soft magnetic layer of the disk. The intensity of the direct current is larger than the anisotropic magnetic field of the soft magnetic layer and is smaller than the coercive force of the recording magnetic layer. As a consequence, the stabilization of the magnetic domain state of the soft magnetic layer of the disk can be realized to make an attempt of decreasing the magnetic noise and establishing stabilization with respect to the disturbance magnetic field.
