摘要： A device inspects the performance of a perpendicular magnetic recording medium by separating the medium noise component of a perpendicular magnetic recording medium to decrease the error rate by accurately separating and detecting the medium noise component. Using correlation matrices, jitter noise and T50 noise which depend on the transition point of magnetization, and DC noise which is added to a DC component are separated and detected from the medium noise component of a perpendicular magnetic recording medium acquired from the reproducing waveform of a magnetic head. By adding a base matrix of the DC noise component to a linear separation expression for detecting the noise power from the medium noise component, the DC noise is detected using the least square method, separately from the other medium noise, which depends on the fluctuation of magnetization transition points.

摘要： In a position control device based on current observer control (114) for performing two degree of freedom control, deterioration of the position accuracy caused by the output delay due to computation is prevented. For preventing overrun, the delay of output of the two degree of freedom control (computing delay and hardware delay of drive amplifier, D/A converter, etc.) is considered, and the estimated state of Td which is advanced by the amount of delay from the sample point of time is computed. The output is then computed based on this estimated state. So even if the state changes during calculation from the sample point of time, the influence of the output delay can be prevented, and highly accurate position control can be performed and overrun can be prevented.

摘要： An atmospheric pressure measuring apparatus allows a transmitter to transmit an acoustic wave for measurement of the atmospheric pressure. Air propagates the acoustic wave. A receiver receives the acoustic wave. Since the intensity of the acoustic wave changes to follow the variation of the atmospheric pressure, the atmospheric pressure can be measured based on the intensity of the acoustic wave received at the receiver. The atmospheric pressure is in this manner measured with such a simplified structure.

摘要： Upon receipt of a read command or a write command from an external device, a disk apparatus stores an obtained address as a primary address and a secondary address in an address storing unit, increments a counter value of the secondary address, and selects the secondary address of which the counter value indicates the largest number. Upon receipt of the read command for the primary address, the disk apparatus reads data specified by the primary address from a disk and stores it in a buffer memory in advance. Upon receipt of the read command, the disk apparatus sends the data from the buffer to the external device.
