Abstract:
A tape drive which transduces information relative to magnetic tape, the tape driving comprising:an encoding unit for encoding data to be recorded with a direct current (DC) content code and which generates a write data signal for DC-code encoded data; a compensation circuit connected to receive the write data signal from the encoding unit and output a compensated write data signal which is corrected for timing distortion caused by the DC content code; a transformer connected to receive the compensated write data signal and to output a transformed write data signal; a write head which records information on the magnetic tape in accordance with the transformed write data signal; and wherein the compensation circuit comprises: a circuit which emulates a high pass filter action of the transformer to provide an emulated high pass filter response signal; a delay circuit which modifies timing of the write data signal in accordance with the emulated high pass filter response signal to output the compensated write data signal.
