发明名称 CIRCUIT FOR DETECTING SIGNAL
摘要 PURPOSE:To output a stable and normal readout pulse signal, by installing an error pulse eliminating circuit provided with a comparator which detects the voltage level polarity of the read out signal of a head in accordance with a voltage signal of threshold level. CONSTITUTION:It is supposed that the level of the read out signal R of a head is lowered as shown in the diagram by a trouble of head crash, etc. When the controller of a magnetic disk device detects a read error corresponding to the trouble, the controller outputs control signals L1 and L2 and determines voltage signals +VR and -VR so that the level of a threshold level signal TH2 is lowered. A comparator 11 detects the voltage level polarity of the read out signal R of the head 1 based on the threshold level signal TH2 and outputs an output signal C0' as shown in the diagram.
