Abstract: A recorded data reproducing apparatus according to this invention comprises a data pulse generation section (l0 to l5), a peak detection section (l7 to l9) and a control section (20 to 22). The data pulse generation section (l0 to l5) reads out data written on the cylinder of a recording medium on which a magnetic head is currently positioned. According to received gain data, the data pulse generation section (l0 to l5) amplifies a signal corresponding to the readout data, and selectively generates data pulse sequence based on the amplified signal. When the amplified signal corresponds to servo data, the peak detection section (l7 to l9) detects the peak value of the amplified signal. The control section (20 to 22) determines whether or not the magnitude of the detected peak value is nearly equal to a predetermined value. If the determination is nega­tive, the control section (20 to 22) refers to a gain data table to determine a change amount of the gain data, and supplies the gain data updated based on the change amount to the data pulse generation section (l0 to l5).

Abstract: In a read circuit for an FDD, a differentiator is constituted by a pair of current control transistors (15, 17) connected differentially, and a series circuit of a capacitor (23), an inductor (25), and first and second resistors (27, 29) connected between the transistors (15, 17). A switch is connected across one (29) of the resistors (27, 29). When a track counter (34) detects an inner track, it supplies an active signal to the switch. The switch is closed to short-circuit the resistor (29), thereby decreasing the damping value of the differentiator.
