摘要: An optical disk drive is designed to read and/or write data from/on a spiral string of tracks where land and groove tracks are alternated. The drive includes: a light source for radiating a light beam; a lens for converging the light beam; a mechanism for moving the lens; a photodetector for generating an electrical signal based on at least a part of the light beam reflected from the optical disk; and a control section for controlling the light source and the mechanism responsive to the electrical signal. While performing a seek operation by having the lens moved by the mechanism such that a target track, from/on which the data should start being read or written, is irradiated with the light beam, the control section tries to get a PLL locked by irradiating another track, which precedes the target track by at least one, with the light beam.

摘要: An optical disc apparatus includes: a defect detecting section 124 for detecting, based on a light detection signal and with respect to a preset detection reference level, a fingerprint or a bubble on the disc 102 as a defect to output a defect detection signal; and a waveform shaping section 126 to output a hold signal that holds, in response to the defect detection signal, a signal from a tracking control section 109 at a level just before the defect has occurred. The apparatus is initially operated not to hold the signal from the tracking control section 109 even if there is a defect. But once a tracking failure has occurred during a read operation, settings are changed to hold the signal from the tracking control section 109 against the defect while the read operation is retried.

摘要: An optical disk drive according to the present invention has the ability to read data from multiple types of optical disks, each of which includes at least one information storage layer. The drive includes: a driving mechanism 120, which is loaded with a selected one of the optical disks of the multiple types and which rotates the optical disk 102; an optical pickup 30 for irradiating the optical disk 102, which has been loaded into the driving mechanism 120, with a converged light beam, thereby generating an electrical signal based on light that has been reflected from the optical disk 102; and a control section (ODC 50) for controlling operations of the driving mechanism 120 and the optical pickup 30. The control section 50 includes a right/wrong side determining section for determining, by reference to the electrical signal generated by the optical pickup 30, whether or not the optical disk 102 has been loaded into the driving mechanism 120 with the other surface opposed to the optical pickup 30.

摘要: After an optical disk drive according to the present invention has been loaded with an optical disk and before the operation of recognizing the type of the given disk is finished, the drive presumes one of multiple types of candidate optical disks, from/on which data is readable and writable using a light beam with the shortest wavelength among the candidate disks, to be the disk being driven by the motor now and gets the beam for the presumed type of disk radiated from a light source (Step (A)). Next, the drive gets the disk spun at a rotational velocity that realizes a linear velocity equal to or higher than a standardized normal velocity when data is read from the presumed type of disk (Step (B)). Thereafter, the drive starts a focus control in a situation where the spot of the beam being formed on the disk is moving on the disk at the linear velocity equal to or higher than the normal velocity (Step (C)). And then the drive performs the operation of recognizing the type of the disk by the light beam reflected from the disk under the focus control (Step (D)).
