摘要： The present invention provides a disc drive apparatus which identifies a type of a disc mounted on the apparatus by using reflected beam data obtained from a laser beam focused on the disc surface and other reflected beam data obtained from the laser beam being focused on the disc signal plane. For example, while forcibly changing the laser beam focusing point within a variable range at a predetermined velocity, a luminous energy signal or a focus error signal is used to count a time difference between a timing of focusing on the disc surface and a timing of focusing on the disc signal plane. According to the time difference obtained, the disc mounted is identified as a first type of disc or a second type of disc.

摘要： 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.
