Title: Magnetic head core
Inventor: NORO TAKASHI
IPC: G11B5/127
Filed: 1988-02-25
Abstract: PURPOSE:To improve reproducing output by suppressing crosstalk by providing second magnetic cores on both side planes of a first magnetic core via a nonmagnetic layer, a first coil which interlinks with both the first and second magnetic cores, and a second magnetic coil which interlinks with the first magnetic core. CONSTITUTION:The second magnetic cores 2 and 2' are provided on both side planes of the first magnetic cores 1 and 1' via the nonmagnetic layers 3 and 3', and two confronting planes which form the recording and reproducing gap of the second magnetic core are provided on the same plane of the two confronting planes which form the recording and reproducing gap of the first magnetic core. Furthermore, the first coil which interlinks with both the first and second magnetic cores, and the second coil which interlinks with only the first magnetic core are provided. Thereby, since track width can be increased when write is performed, and the track width can be decreased when readout is performed, and recording width 15 for a recording medium 12 can be widened, no lowering of output occurs even when the deviation of a track position is generated in a readout operation. Also, since no magnetic flux from a adjacent track passes the first magnetic core 1, the crosstalk can be suppressed.

Title: Distortion correction circuit
Inventor: YAMAGUCHI HIROYASU
IPC: H03F3/50
Filed: 1979-04-11
Abstract: PURPOSE:To obtain a distortion correction circuit which is suited for the emitter follower circuit or the like. CONSTITUTION:The distortion correction circuit is constituted with constant current source TrQ2 plus its bias TrQ3 and Q4 to emitter follower transistor TrQ1. The output signal is led to TrQ4 featuring nearly same value to load resistance RL in the form of emitter resistance RE to be set to nearly same current value as the AC load current. And the AC current of the reverse phase is generated for the cancel use and then fed back to TrQ1 via TrQ2 and Q3 which form the current Miller circuit. In this case, the cancel-use AC current grown from TrQ4 is followed by the distortion component. And if the distortion is 1%, the overall distortion becomes as 1%X1%=0.01%. In such way, a big distortion reduction effect is secured, thus ensuring a correction of the distortion up to such amount that can be ignored substantially.
