Patent number: 4716557Abstract: An information selection device of a disc player comprises a pickup device (1), a signal processing circuit (12) and a moving device (16). The signal processing circuit (12) comprises a read circuit (13), a write circuit (14) and a comparator (15). At the time of searching a desired piece number and a desired index, these desired piece number and index are written in the write circuit (14). The pickup device (1) radiates a light beam on a disc (8) so that the piece number and the index of the track traced at present are detected by the read circuit (13) at predetermined time intervals from the beam modulated and reflected on the disc (8). Then, the detected piece number and index are compared by the comparator (15) with the desired piece number and index written in the write circuit (14).Type: GrantFiled: March 4, 1986Date of Patent: December 29, 1987Assignee: Sanyo Electric Co., Ltd.Inventor: Kiyoshi Otani
