摘要： A tracking controller includes a tracking error detecting section and a tracking control section. The tracking error detecting section generates and outputs a tracking error signal that represents how much the focal point of a light beam has shifted from a target track on a storage medium. The tracking control section generates a drive signal in response to the tracking error signal so as to move the light beam such that the focal point of the light beam is located right on the target track. The gain of at least one of the tracking error signal and the drive signal is switched depending on whether or not the focal point of the light beam is located on a recorded area of the storage medium on which data has already been written.

摘要： A drive apparatus for driving an information recording medium encased in a cartridge has a protection element for protecting the recording medium. The drive apparatus has an action member for cooperating with the protection element. The action member is projected out of the apparatus when the cartridge is inserted into the apparatus, and remains in the apparatus when the cartridge is detached from the apparatus. The apparatus comprises a drive unit and a cartridge mounting unit disposed on a base body of the drive unit. The cartridge mounting unit han an operation button disposed at a position which is furthest apart from the attached cartridge and opposite to the base body with respect to the attached cartridge. When the recording medium is a flexible disk, the disk is pressed onto a recording or reproducing head by a pad. An arm for supporting the pad allows the pressure exerted by the pad on the disk to increase with the rotation of the disk.

摘要： A disk access device records to and plays back from a disk on which data recording is performed according to the ZCLV format, and includes a head that reads/writes data from/to the disk. The disk access device calculates a deferment time period that begins upon completion of data reading/writing in the user area of a currently accessed zone and ends when the head enters a predetermined area of the guard track zone following the user area, and a setting time period for performing settings for data reading/writing in the zone to be accessed next. If the deferment time period is shorter than the setting time period, the disk access device moves the head back, when data reading or writing in the currently accessed zone ends, to a position such that the setting time period ends before the head advancing from the position arrives at the predetermined area.

摘要： In order to correct the change in the offset and amplitude of a tracking error signal because of the change in the position of an object lens from the center of an optical pickup, the offset amount and amplitude value of the tracking error signal with respect to the displacement amount of the object lens from the center of the optical pickup are checked beforehand, and the displacement amount of the object lens is estimated on the basis of a tracking correction signal by using an object lens displacement observer. An offset detection section and an amplitude detection section detect the offset amount and amplitude value of the tracking error signal respectively, and the tracking error signal is corrected by an offset correction circuit and an amplitude correction circuit on the basis of the offset amount and amplitude value having been checked beforehand so that the offset amount and the amplitude value of the tracking error signal become identical to those obtained when the displacement amount of the object lens is zero. In addition, the offset of the tilt error signal depending on the movement direction of the optical pickup 2 is detected and recorded beforehand, and the tilt error signal is corrected on the basis of the above-mentioned recorded offset when a rotation direction detection section detects the moving direction of the optical pickup.
