摘要： A medium storage device writes or read data on a storage medium synchronizing the rotation of the storage medium with the DSW method for decreasing the gap length considering the rotation jitter. The medium storage device has a controller for generating synchronization timing signals during reading/writing from a clock, and a processing unit for calculating the correction value of the frequency from the measurement result of the servo synchronization mark space of the storage medium. The processing unit judges whether or not the detected interval of the servo synchronization marks is within a predetermined range which is not occurred a frequency compensation to influent an error rate when reading, and corrects the synchronization timing of the controller based on the interval of the servo synchronization marks when the detected interval is judged within the predetermined range.

摘要： A magneto-optical recording medium processing apparatus of the present invention limits, via a predetermined current limiting means, the bias current applied to a bias coil during seek, when a seek current is applied to a carriage. In accordance therewith, it is possible to reduce the peak of the sum current, which is the total of the seek current and the bias current, and the current consumption of the entire apparatus can also be curbed. Current limiting means, for example, sets a bias current that is smaller than the specified value of the bias current required at media access time, and sets a bias current value such that the total of the seek current and bias current does not exceed an allowable current.

摘要： When an access of a 1-track seek is instructed from an upper apparatus, a 1-track seek period is divided into predetermined accelerating period and decelerating period. A decelerating current is determined in accordance with a difference between sample points before and after a zero-cross point of a tracking error signal E2, namely, a beam velocity with respect to the decelerating period and is supplied. With regard to a fine seek as well, the decelerating current is determined from the beam velocity obtained from the difference between the sample points before and after the zero-cross point just before a target track and is supplied.
