Magnetic tape recording device having a rectifier installed on a rotating head drum for rectifying a signal being applied to the head

摘要

In an arrangement for inductive transmission of a data signal to the recording head (9) in a magnetic tape recording device, in which the data signal to be transmitted to the recording head is delayed by a bit period, the undelayed signal and the delayed signal are combined and applied to an inductive transmission arrangement (11, 13). After passage through the inductive transmission arrangement, the combined signal is rectified in a rectifier (21) and then subjected to a DC voltage shift (22). The resultant signal is then amplified (10) and applied to the recording head.
