Abstract
PURPOSE:To prevent an over-compensation in an equivalent circuit and to attain the reading with a high reliability by selecting plural equivalent circuits for a reading signal through a logic circuit and a selecting circuit in accordance with an address signal corresponding to a storage position. CONSTITUTION:When a selecting signal outputted by a logic circuit 13 corresponding to an input address signal 12 in accordance with the storage position of a disk is supplied, a selecting circuit 10 selects either of equivalent circuits 2-5 corresponding to four areas of the area to divide the radius direction of a disk into five or a reading signal 1 without passing through the circuits 2-5. By the proper equalization, the over-compensation of the equivalent circuit due to the characteristic difference by the inner and outer circumferences of the disk is prevented and the reading with a high reliability can be executed.
