    Abstract: After the initiation of writing, an output signal from an LPF is sampled in correspondence with a portion with a predetermined pulse width of recording data, so as to obtain a pit level. In the resultant signal, its varying portions which correspond to the multi-pulse trains of the write signal are smoothed. A controller modifies a level of a target level signal to be supplied to an APC circuit in such a manner that the pit level becomes an optimum pit level which has been obtained prior to the initiation of writing.

    Abstract: A laser light beam is illuminated via an objective lens on the signal surface of an optical disc and the objective lens is displaced by a servo processor along the optical axis for focussing search to generate focussing error signals by a RF block from a detected output of the laser light by the signal surface of the optical disc. Based on these focussing error signals, a system controller discriminates the types of the optical disc having different numbers of signal recording layers for setting an operating mode in keeping with the types of the optical disc.

    Abstract: PROBLEM TO BE SOLVED: To appropriately conduct data reading and writing for an optical disk, in which a recording density is made high, while maintaining the interchangeability with an optical disk having an existing format. SOLUTION: The wavelength of optical beams, with which an optical disk is irradiated, is set to 780 nm and a numerical aperture NA of an objective lens is set to 0.50±0.01 or 0.55±0.01. When signal reading and writing are conducted for a double density CD-R, the CD-R is rotated with an N times linear velocity (where N is the magnification with respect to a standard velocity) of 0.9±0.05 m/sec and the characteristic of an equalizer is boosted and set in the vicinity of the frequency, that is N times 1 MHz, so as to obtain 3 to 4 dB gain.
