Multichannel digital magnetic recording apparatus |
摘要 |
A multichannel digital magnetic recording apparatus comprises a plurality (N) of modulating circuits (41 to 4N) and timing circuits (51 to 5N). Digital signals (Z1 to ZN) undergo modulation in the modulating circuits in accordance with a modulation system of a detection window Tw. The modulated signals (A1 to AN) are converted into pulse current trains by the timing circuits and then delayed such that the respective pulse currents do not occur simultaneously. Accordingly, a power capacity required of a voltage source for writing the signals by means of thin film magnetic heads (71 to 7N) is considerably decreased.
