Recording method to magnetic tape
专利汇可以提供Recording method to magnetic tape专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the distortion and frequency characteristics, by splitting an input signal into a plurality of bands, and setting an optimum bias value to the respective bands for recording and reproduction. CONSTITUTION:An audio signal of the 1st channel is inputted to an input terminal Ti1 and the signal is applied to a low pass filter 161 and a high pass filter 162 via an amplifier 151. The output of each filter is respectively inputted to equalizers 171 and 172, where equalization is performed so that the frequency characteristics around the crossover frequency can be made flat in reproducing the content of recording of a magnetic tape 1. The output of each equalizer is applied to the 1st and 2nd heads 7 and 8 through a recording terminal of a recording/reproducing changeover switch 13 via driving circuits 181 and 182. On the other hand, an optimum bias current is applied to each band of heads 7 and 8. The audio signal of the 2nd channel is similarly split into a high and a low frequency audio signal, which are recorded with the optimum bias current respectively.，下面是Recording method to magnetic tape专利的具体信息内容。
