Abstract: Embodiments of the present invention provide a disk drive capable of reducing, by means of simple control, vibrations applied to the drive and vibrations occurring in the drive, and a control method for controlling the disk drive.

Abstract: Embodiments of the invention are directed to detecting an abnormality in head flying height. In one embodiment, an AGC controller establishes the gain of the reproduced signal through gain adjustment using the servo AGC of the servo signal. A digital filter performs filtering processing by use of the obtained gain data g and the gain data of previous sectors. A comparative judgment section obtains filtered gain data G from the digital filter and compares the gain data G with a reference value CRITERIA to determine whether the flying height is normal or abnormal. If the gain G is larger than the reference value CRITERIA, then the data write operation is inhibited. The filter parameters of the digital filter are programmable parameters which can be set and changed.

Abstract: A semiconductor memory device includes a RAM and a serial access memory (SAM). The SAM includes an address counter which generates a slave address and a master address. The slave address precedes the master address by half the period of a serial access strobe signal. A redundancy decision is made by comparing the slave address with a redundancy address. When the master address is supplied to a data register provided in the SAM, the decision result is available. That is, the SAM can be accessed immediately after the master address is supplied thereto.
