发明名称 WRITE CIRCUIT
摘要 PURPOSE:To shift a peak at the side of a magnetic recorder and to correct the timing of information by detecting information for showing the minimum current inverting interval of recorded information and reducing the current amplitude in the minimum current inverting section after receiving the signal of the information. CONSTITUTION:The inversion timing b' of a current flowed into the coil of a magnetic head is applied to the inverter 12 of a write circuit, an OR circuit 15 and a delay circuit 20. A signal d' from the circuit 15 is applied to a re- triggerable monostable multiplexer 14, and an output f' and a signal e' from the circuit 20 are ORed at an OR circuit 16 and an AND circuit 17 and outputs h' and g' are applied to an SR-FF18. A signal i' at a high level, where the pulse interval of a memory information signal is taumin, is outputted to the output Q of the FF18, and applied as the current limiting signal of the coil 5 to a diode connection TR24 connected to switching transistors TRs 2 and 3 through a diode 21. The signal e' from the circuit 20 is applied to the TRs 2 and 3 through buffers 22 and 23, thereby correcting the timing of the memory informa tion.
