    摘要: A vibration extraction processing unit extracts a deflection component synchronous with a rotation from a clock signal of a non-contact sensor so as to correct a clock jitter. A clock generating unit generates a clock signal of any format frequency preliminarily set up according to the clock signal from the vibration extraction processing unit. A sector correction processing unit measures an error due to the frequency deflection so as to correct the writing start position for the format pattern signal of each sector containing a servo frame signal stored in a memory according to the measured error. Writing processing units read out the corrected format pattern signal from the memory according to a synchronous signal corresponding to a single turn of a disc and a format frequency clock signal and then writes into a disc medium face.

    摘要: There is provided a servo information recording device having a simple structure, being implementable in lower cost, and capable of writing servo information with high reliability and a servo information recording method.A servo information recording device comprises: a head swingably supported relative to a predetermined swing axis; a head drive section that swings the head within a predetermined zone in the radial direction of the disk medium; and a controller that controls the head drive section and writes the servo information onto a track of the disk medium. Assuming that R is the outer circumferential radius of the disk medium and P is a distance between the center of the disk medium and pivot (swing axis), the swing axis is disposed at a position at which P/R falls beyond about 1.35.

    摘要: The method of the present invention is capable of shortening the time required for positioning an inner actuator and writing servo track signals on a magnetic disc, and improving the quality of the written servo track signals. The amount of displacement between the inner actuator and an external actuator is detected with a present position of the external actuator. A first deviation between a travel destination of the external actuator and a present position of the inner actuator is detected on the basis of the amount of the displacement, the present position of the external actuator and the travel destination thereof. The inner actuator is controlled so as to make the first deviation within a predetermined standard range.

    摘要: A storing unit stores first correction information for correcting a distortion synchronized with a rotation frequency of servo information of a first disk. A control unit controls positioning of a head on a target track by correcting the servo information of the first disk with the first correction information. Measurement information used for measuring the first correction information is calculated based on second correction information for the servo information in other disk apparatus including a second disk on which the servo information is formed using a common master medium with the first disk.
