Title: Magnetic recorder and reproducer
Inventor: MIZUGUCHI NOBUAKI
IPC: G11B5/03
Filed: 1982-04-14
Abstract: PURPOSE:To improve the high band frequency characteristics without deteriorating the distortion of the middle/low bands, by using a normal head to have the optimum bias recording at the middle/low bands and then using an inclined head to have the obtimum bias recording at a high band respectively and synthesizing the outputs of both heads when the reproduction is carried out. CONSTITUTION:The signal of an input terminal 15 is supplied to recording amplifiers 3 and 9. A normal head 1 records the signal amplified by an amplifier 3 to a magnetic recording medium 12 by a bias oscillator 2 with the optimum bias at a middle band. At the same time, the signal amplified by the amplifier 9 is recorded to the medium 12 by a bias oscillator 9 and an inclined head 6 via an HPF7 with the optimum bias at a high band. In the reproduction mode, only the signal recorded by the head 1 is reproduced and then applied to an LPF5. The head 6 reproduces the signals recorded by both heads 6 and 1 and then applies these reproduced signals to an HPF11. Then the signals passed through the LPF5 and HPF11 are synthesized. In such a way, the high band frequency characteristics can be improved without deteriorating the distortion of the middle/low bands.
