Abstract: A central magnet of a plurality of magnets arranged to be different in polarities is detected by two hall ICs; therefore, reduction in size can be achieved by reducing the number of the magnets; and at the same time, the number of the hall ICs can be maintained and the reliability can be secured, as compared with a configuration in which the magnets and the hall ICs individually respond in one to one correspondence.

Abstract: Embodiments of the invention improve the efficiency of communication processing between a host and a storage device. In one embodiment, a data processing system includes a storage device and a host. The host gives the storage device an instruction to perform specified processing, and an instruction as to whether or not a completion notification of the instructed processing is to be transmitted to the host. If the host instructs the storage device to transmit a processing completion notification, the storage device transmits the completion notification to the host. On the other hand, if the host instructs the storage device not to transmit a processing completion notification, the storage device does not transmit the completion notification to the host.

Abstract: Embodiments of the invention relate to measuring characteristics of a head with an actuator put in a state of being pushed against a crush stop. In one embodiment, with a head placed on an innermost ID side or with the current of a VCM sustained at a magnitude I_mid, a burst pattern is written onto a recording disk. At this stage, the gain of a VGA is equal to its maximum value Gmax. Then, while the current of the VCM is being changed gradually, the gain of the VCA is measured. As the current of the VCM becomes equal to a magnitude I_center, a read element of the head is positioned right above the burst pattern. At that time, the gain of a VGA is equal to its minimum value Gmin. As the read element is further moved to the OD side, the gain of the VGA again becomes equal to the maximum value Gmax. A read/write offset of the head is identified by the magnitudes I_center and I_mid.

Abstract: An optical disc drive compatible with optical discs of different types, for example, is provided. For focusing, through an optical system used in common with the different types of optical discs, a laser beam emitted from a selected one of a plurality of light sources disposed apart from each other radially of the optical disc, the optical system is moved radially of the optical disc correspondingly to the selection of the light source for emitting the laser light. Namely, it is possible to prevent the optical property from being deteriorated when a single optical pickup is used in common with such optical discs of different types.
