Title: Magnetic head
Inventor: HOSOKAWA MINORU
IPC: G11B5/187
Filed: 1983-02-03
Abstract: PURPOSE:To obtain a head suitable for high-density recording by allowing the 1st magnetic core to leave a thin-film magnetic pole on its medium facing surface and come close thereto at distance from the medium facing surface, and permitting the 2nd magnetic core to face the thin-film magnetic pole on the medium facing surface to nearly equal width. CONSTITUTION:A hatched part in a figure is a magnetic core part and consists of three members. Part of a soft magnetic core is wound with a coil 602 for recording. Core member 601 and 604 face each other at a proper interval and a magnetic pole 603 for recording and reproduction is interposed between the members 601 and 604. Flows of magnetic flux in recording and reproduction is shown by a solid-line arrow 901 and a broken-line arrow 902 respectively. When a current for recording flows through the recording coil 602, a recording magnetic field is established between the magnetic core members 601 and 604. The magnetic field between the core members converges to the thin-film magnetic pole 603 because of the presence of the magnetic pole 603 between both members to flow magnetic flux as shown by the solid-line arrow 901. Consequently, a medium is magnetized for recording by the magnetic field which converges to the medium facing part at the tip of the magnetic pole.

Filed: 1982-02-03
Abstract: PURPOSE:To eliminate a common mode noise by performing sampling operation which synchronizes with a commercial power source frequency and regarding the sum of several sampled values as a final result. CONSTITUTION:Sampling is carried on 3X2<n> times within one cycle of the commercial power source frequency and sampled values are A/D-converted and summed up for one cycle.

Now, if n=1 and the output of the A/D converter 6 consists of 12 bits, the processing output of a CPU10 consists of 15 bits and 1 is only added as the LSB to realize the value of an input voltage which is easy to handle directly. When the input voltage is 5V, 5,000 is outputted as 16-bit data.
