Title: Magnetic head
Inventor: TAMASO HARUO
IPC: G11B5/127
Filed: 1987-10-29
Abstract: PURPOSE:To perform stable recording operation without bringing a magnetic head and a magnetic recording medium into contact with each other by forming sharp magnetic flux by a thin hole or thin slit formed in a superconductor. CONSTITUTION:The superconductor 1 and thin hole or thin slit 2 provided in it are used for a generation part for a magnetic field to be supplied to the magnetic recording medium 6. The superconductor 1 cuts off the magnetic flux completely by its Meissner effect. The thin hole 2 formed in the superconductor 1, on the other hand, can pass the magnetic flux naturally. When it is provided in a magnetic path, the magnetic flux flows out of only the thin hole part 2, so a beam-shaped magnetic flux flow is obtained depending upon the thin hole 2. Consequently, a signal can be recorded on the magnetic recording medium without making the magnetic head contact the recording medium.

Title: Trigger signal generating circuit
Inventor: FUIRITSUPU II DEEBAA
IPC: G11B20/02
Filed: 1987-10-29
Abstract: PURPOSE:To trigger a device when a continuous signal is broken or interrupted by outputting a trigger signal when the generation interval of a prescribed signal is not within a prescribed range. CONSTITUTION:The threshold value level of a trigger circuit 201 is set slightly lower than the peak amplitude of the continuously inputted signal. Then the circuit 201 is so set as to generate an output pulse when the continuous input signal crosses the threshold value positively. Alarm counting of a timer circuit 203 is set to an interval slightly longer than the period of the continuous input signal. Therefore, as long as the amplitude and frequency of the continuous input signal are constant, the circuit 201 resets the circuit 203 before the alarm counting is reached, and a measurement signal is not generated with a dropout trigger signal. Then when the continuous input signal decreases in amplitude and never exceeds the threshold value level for a period of >=1 cycle, the circuit 203 reaches the alarm counting a prescribed time later to generate a trigger signal, thereby analyzing various phenomena in the break state of the signal.
