摘要： Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.

摘要： A correlation signal generating circuit generates a duplicate signal for correlation processing based on a multiplex duplication signal. An autocorrelation circuit performs autocorrelation processing through sliding processing of the duplicate signal with respect to a received signal. An Nd detecting circuit detects the length of the data symbol by detecting a correlation value peak obtained based on the guard interval symbols. A data correlation circuit performs mutual correlation processing on the extracted data through the sliding processing by changing the window sizes. An Ng detecting circuit detects the length of the guard interval symbol by detecting the correlation value peak which is obtained when the guard interval symbol length and the window size become consistent.

摘要： A packet transmission control device and a packet transmission control method for reducing degradation of system throughput due to a wireless mobile station in an abnormal state, in controlling transmission of packets to each of a plurality of wireless terminals. A channel is assigned based on an evaluated value from an evaluation function containing an average transmission rate value for the wireless terminal in its denominator, and if the evaluated value falls in an abnormal value, the average transmission rate value is initialized to reduce the frequency of assigning packets to the wireless terminal if one of multiple wireless terminals transitions to an abnormal state. By initializing the average transmission rate value, a phenomenon that an unnecessarily large number of shared channels are assigned to a wireless mobile station in an abnormal state may be avoided to prevent degradation of overall system throughput.
