An optical disc drive according to the present invention can read data from any of multiple types of optical discs, of which the information storage layers are located at mutually different depths under their surface. When this drive is loaded with an optical disc, the servo controller of the drive changes a first type of drive signal to adjust a focus position by changing distances from the lens to the disc and/or a second type of drive signal to adjust tilt of the lens by changing the angles defined by the lens with respect to the disc a number of times, thereby changing settings to be determined by a combination of the focus position and the tilt. A signal quality rater measures multiple index values to rate the quality of a reflected light signal as the settings are changed. Then, the optical disc drive recognizes the type of the given optical disc based on those index values and reads data from the optical disc recognized.

A depuncturing unit depunctures a punctured convolutional code sequence and outputs the result to a decoding execution unit. The decoding execution unit executes Viterbi decoding, and it includes an ACS processing unit with a variable radix. A radix control unit controls a radix of the ACS processing unit according to a puncturing rate indicating a degree of puncturing of the convolutional code sequence which is acquired by a header analysis unit in a subsequent stage, in such a way that the radix of the ACS processing unit is larger as the puncturing rate is higher.
摘要:
A multilayer filter comprises an inductor stacked-layer portion and a varistor stacked-layer portion. The varistor stacked-layer portion has a varistor layer the main component of which is ZnO and a hot electrode and ground electrode positioned in opposite with the varistor layer intervening, and the region enclosed between the opposing hot electrode and ground electrode does not contain a Cu component. Because the region enclosed between the opposing hot electrode and ground electrode is a region which manifests varistor characteristics, and thus the region does not contain a Cu component, degradation of the attenuation characteristics can be suppressed.
