ABSTRACT:
A recorded data reproducing apparatus according to the invention includes a memory section having a gain data table for storing gain data determined in accordance with a cylinder position above a recording medium. Using the data representing the current cylinder position, the optimum gain data is determined from the gain data table, and supplied to a read pulse generator section under control by a control section. With this arrangement, the gain adjusting circuit is simplified, and the gain adjustment process is also simplified.
