Embodiment Construction

[0029] Next, an example of an optical disc device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0030]

[0031] First, the structure of an optical disc device according to the present invention will be described with reference to the drawings. 1 is a block diagram showing a structural example of an optical disk apparatus according to the present invention, and FIG. 2 is a block diagram showing a structural example of an optical system of the optical disk apparatus according to the present invention.

[0032] (structure)

[0033] As shown in FIGS. 1 and 2, an optical disc apparatus according to the present invention has an optical pickup 2 for irradiating laser light on a disc D driven by a disk motor 1, or receiving reflected light thereof, and an RF amplifier 3, the pickup The read signal in 2 is supplied to RF amplifier 3. The optical disc device also has a signal processing unit 4 to which ...

Abstract

There is provided a disk device including a detector section which generates detection signals according to reflected lights of laser lights emitted on a disk, a removing section which detects detrack components which have failed to detect recording information on the disk from the detection signals and removes and outputs the same from the detection signals, and a processing section which applies a predetermined processing on the basis of signals obtained by removing detrack components from the detection signals, so that erroneous address information on CAPA which has been failed to read or the like can be removed, thereby improving reading accuracy of the disk.

Description

technical field [0001] The present invention relates to a disk device (disk device) and a disk processing method, and more particularly to a disk device and a disk processing method for eliminating reading failures such as CAPA (Complimentary Allocated PitAddress) and the like, so as to improve reading accuracy method. Background technique [0002] In recent years, as the development and distribution of optical discs or optical disc devices has progressed, the capacity of optical discs has become larger and larger, and therefore the control system of the optical disc device requires high operational reliability. [0003] In an optical disc recording / reproducing device, in a medium in which pits are recorded in lands and grooves provided by DVD-RAM, CAPA (Complimentary Allocated ID (Identification Data) of the Pit Address) in order to obtain the address and information of whether the currently tracked pit string is in a land or in a groove. Thus, when the ID reading perform...
