摘要： The present invention provides a disc drive apparatus having an improved tracking control and seek time adjustment. The head tracking error distribution along the disc radius is determined with reference to the phases of a plurality of position sensors and is calculated based on the tracking error of a reference track in first and second reference regions with respect to the signal from one of the position sensors. This information is used to determine the tracking error distribution along the disc radius with respect to that one of the position sensors. The tracking error distribution is used to determine the tracking error of a reference track in a third reference region with respect to the signal from the same position sensor. This tracking error is used to determine the tracking error of other reference tracks in the third reference region with respect to the signals from other of the position sensors. The tracking error of the reference tracks is then used to determine the tracking error of the data tracks on the disc. The present invention also provides a disc drive apparatus having an automatic seek time adjustment. A predetermined number of tracks is moved through based on a set head velocity. The seek time is compared to a prescribed seek time. If the two times differ, the velocity is adjusted until the prescribed seek time is achieved.

摘要： There is provided a disk drive in which a base lifting mechanism (93) makes a first disk chucking operation to place an optical disk (2) on a disk mount (27) by elevating at least a base (31) to a disk chucking position, lowers the base (31) to an intermediate position between the disk chucking position and a disk releasing position so that a disk rotation driving mechanism (28) spins the optical disk (2) which will thus take another phase, elevates the base (31) to the disk chucking position again, and makes a second disk chucking operation to place the optical disk (2) on the disk mount (27). Thus, the optical disk can positively be chucked onto the disk mount.

摘要： A magnet-optical disk drive device comprises a disc driving mechanism which includes a drive shaft powered by an electric motor. A magnet-optical disc is detachably connected to the drive shaft. A magnetic field modulation head is positioned at one side of the disc, and an optical unit is positioned at the other side of the disc. A moving mechanism is employed for moving both the magnetic field modulation head and the optical unit in a radial direction of the disc. The magnetic field modulation head is of a floating type wherein a head proper is forced to float above the surface of the disc due to the force of an air flow which is produced when the disc is rotated.
