    摘要: A method for controlling a semiconductor memory in which mode register can be set in burst mode. To set an operation mode in burst mode, the semiconductor memory is changed first from the burst mode, through power-down mode, to standby mode of non-burst mode. Then the semiconductor memory is changed to mode register set mode to set the mode register when commands are input in the same predetermined sequence that is used in the non-burst mode.

    摘要: Embodiments of the invention provide a disk drive capable of writing information on data tracks even more positively when a shingle write method is adopted. In one embodiment, the disk drive is characterized in that, when information is to be written on a plurality of adjacent data tracks on a recording medium through the shingle write method, writing of information is controlled by detecting an actual writing position based on servo information recorded on the recording medium and determining whether or not the detected actual writing position meets a predetermined condition.

    摘要: Embodiments of the invention provide an information recording device that can control the timing of information recording on a patterned medium, with a simplified configuration, and a control method for the information recording device. In one embodiment, an information recording device is provided which has a read/write head opposed to a patterned medium and moving in a relative form with respect to the patterned medium and is used to record information on the patterned medium. In accordance with a signal that the read/write head reads out from the patterned medium, a clock signal generator generates a clock signal pertaining to the timing in which the read/write head moves above the recording regions of the patterned medium, and information is recorded on the patterned medium in accordance with the information recording timing of the read/write head that has been determined in the relationship with the above-generated clock signal.

    摘要: A semiconductor memory includes a refresh timer and an arbiter for determining the order of precedence between an access operation and a refresh operation, in order to automatically perform refresh operations inside the memory. A detecting circuit operates in a test mode and outputs a detection signal indicating that the refresh operation is yet to be performed, when a new internal refresh request occurs before the refresh operation is performed. For example, the detection signal is output when the interval of access requests is short and no refresh operation can be inserted between the access operations. That is, in the semiconductor memory in which refresh operations are performed automatically, it is possible to evaluate the minimum interval of supplying access requests. As a result, the evaluation time can be reduced with a reduction in the development period of the semiconductor memory.

    摘要: A hard-disk drive. The hard-disk drive includes a magnetic-recording disk in which tracks adjacent to each other are magnetically separated, a spindle motor which drives the magnetic-recording disk, a magnetic-recording head equipped with write element and read element, an actuator for positioning the magnetic-recording head on a predetermined track on the magnetic-recording disk, and a control unit. The control unit is configured to store information about an over-write-only track that is provided for a plurality of tracks including n consecutive tracks in at least a partial radial area of the magnetic-recording disk and an offset amount. In a radial area of the magnetic disk where the over-write-only track is located, the control unit is configured to record with an offset by an offset amount from a center of a track toward the over-write-only track with respect to n−1 tracks of the plurality of n tracks, excluding the over-write-only track.
