Abstract
An ADR (advanced digital recording) system for reading and writing information on a magnetic tape using a thin film head (1) with a read part and a write part, whereby track sensing signals on the tape can be read out and data signals can be written on the tape and read out, comprises a preamplifier (2) and, connected thereto, readout channels (3, 4) for track sensing signals and data signals, as well as a low pass filter for the track sensing signals. Both the channel separation for track sensing signals and data signals and the filtering of track sensing signals take place in the preamplifier (7, 8) provided on an IC.
