Title: Information reproducing device
Inventor: TAKIZAWA MINORU
IPC: G11B7/135
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To suppress the level of a leak-in signal more surely by making the transmission state of light beams in the sectional plane of an optical path settable while changing the transmissivity and/or the shape of a mask area to make a device cope with objective areas of reproduction flexibly. SOLUTION: Reading of information recorded in respective zones of an optical disk is performed by changing the mask pattern of an EC plate 17h and, moreover, ratios of levels of leak-in signals with respect to the levels of recording signals (signal ratios) are calculated as to mask patterns suppressing the levels of leak in signals. A master control circuit 21 recognizes optimum maser patterns of respective zones by storing ON/OFF information of maser patterns with which these signal ratios become the smallest in a correspondence table by associating them with respective zone numbers. Thus, the level of the leak-in signal is surely suppressed by the maser patterns to be set to the EC plate 17h based on this correspondence table.
