Title: Bias oscillator for tape recorder
Inventor: NAKAMARU MUTSUMI
IPC: G11B5/03
Filed: 1984-08-16
Abstract: PURPOSE:To prevent fluctuation in an oscillated frequency by using a pulse oscillation circuit not using any coil to drive a separatedly excited oscillator thereby forming a bias oscillating circuit. CONSTITUTION:An output of an astable multivibrator 1 as a pulse oscillation circuit is converted into a sinusoidal wave by a waveform converting circuit 2. The sinusoidal wave is converted into sinusoidal wave signals opposite in phase to each other by a phase converting circuit 3. Separatedly excited oscillators 4A, 4B are driven respectively by the sinusoidal wave signals of opposite phase to each other. Then a bias frequency is outputted from both the oscillators 4A, 4B and the output of them is fed to an erasure head H1 and a recording/reproduction head H2. Thus, the oscillating frequency of both oscillators 4A, 4B is controlled by the pulse oscillating circuit 1. Since the bias oscillating circuit is formed in this way, the fluctuation of the oscillated frequency is prevented.
