SIMULTANEOUS RECORDING TYPE MAGNETIC RECORDER

摘要

PURPOSE:To suppress crosstalks and make possible high density recording by weighing and adding to plural input signals to change recording currents and parallel- recording these in respective tracks. CONSTITUTION:One of the input signals being applied to terminals 5a, 5b is applied to a main recording amplifier 13a and the other to an auxiliary recording amplifier 14a. The amplifier 14a generates the compensating current weighed by the signal being applied to the terminal 5b. This compensating current and the recording current outputted by the amplifier 13a are added in an adder 15a and is applied to the winding 3a of a head 17a, then the signal applied to the terminal 5a is recorded in a magnetic tape 7. In a similar manner, the input signal from the terminal 5b is recorded in other track with a head 7b and the recording signal of the head 7a is not recorded in the track of the head 7b owing to crosstalk. The same also results with the track of the head 7a. Hence, the good multichannel parallel magnetic recording free from crosstalks may be preformed by narrowing the intertrack spacing.
