Abstract
PURPOSE: To achieve small size and cost down, by using the magnetic switch element showing rapid magnetization inverting phenomenon to the change in magnetic field as the signal detection means and converting the rapid magnetic field change into the electric signal of pulse or digital signal.
CONSTITUTION: In constituting the magnetic head 9 through the use of rod-shape Wiegand effect type magnetic switch element 1, the detection coil 10 is wound as the magnetic detector around the magnetic switch element 1, it is connected to the external output terminals 13, 14 with the lead 11, 12, it is magnetically shielded with the shield cores 15, 16, to form the closing magnetic path including the gap. Since pulse output is appeared at the output terminals 13, 14 accompanied with the running of the magnetic tape 25, after this is amplified at the amplifier 31, it is separated into positive and negative pulse at the separation circuit 32 and they are fed to the set and reset terminal of the flip flop circuit 33, allowing serial digital signal to be demodulated and outputted.
