<p>MAGNETIC RECORDING APPARATUS A magnetic recording apparatus comprised of a plurality of magnetic recording heads for recording an input signal on a record medium, the recording heads are selectively supplied with a bias current superimposed on the input signal to be recorded so that a selected one of the heads is rendered operative in accordance with the amount of bias current supplied thereto so as to record the input signal. The operability of the recording heads is controlled to be a function of the position of the heads with respect to the record medium.</p> |
