Title: Magnetic disk device
Inventor: UEDA JIYUNSAKU
IPC: G11B5/09
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To enhance recording density of data for a magnetic disk. SOLUTION: This device is provided with magnetic heads 202a, 202b with azimuth angles different from each other. When a signal is recorded/reproduced for an even number track as the target track of the magnetic disk 201, a changeover switch 212 is connected to an (a) side, and the magnetic head 202a is placed on the target track by a position control circuit 221, and the signal is recorded/reproduced by the magnetic head 202a. On the other hand, when the signal is recorded/reproduced for an odd number track as the target track of the magnetic disk 201, the magnetic head 202b is placed on the target track by the position control circuit 221, and the signal is recorded/reproduced by the magnetic head 202b.  Since the signals are recorded/reproduced for the adjacent tracks of the magnetic disk 201 by the magnetic heads with azimuth angles different from each other, the necessity of providing guard bands preventing crosstalk from the adjacent tracks among respective tracks of the magnetic disk 201 is eliminated.

Abstract: PURPOSE:To ensure excellent weatherability, enable pits to be formed uniformly along the entire circumference of a track and enhance recording and reproduction characteristics, by sequentially providing a selenium layer, a gold layer, a tellurium layer, a gold layer and a selenium layer on a base to provide a recording layer. CONSTITUTION:A selenium layer 2, a gold layer 3, a tellurium layer 4, a gold layer 5 and a selenium layer 6 are sequentially provided on a base 1 to provide a recording layer.

It is considered that the surface tension of the tellurium layer 4, which is a main factor of the change in reflectance on forming the pits, is changed by the presence of the gold layer 5, and that the difference in surface energy due to the presence or absence of the tellurium layer 4 is changed by the presence of the gold layer 3, and consequently that the pits become less liable to be broadened.

Title: Offset correction circuit for differential amplifier
Inventor: YAMANAKA TOSHIHIRO
IPC: H03F3/45
Filed: 1985-05-20
Abstract: PURPOSE:To correct an offset voltage without deteriorating the frequency characteristic by connecting a constant current source to a cascode connecting point of a differential amplifier and adjusting the current so as to correct the offset voltage of the differential amplifier. CONSTITUTION:Transistors (TR) Q6, Q7 constituting a constant current source are connected respectively to emitters of TRs Q3, Q4 and a variable resistor RV adjusting a current flowing to the TRs Q6, Q7 is connected between the emitters of the TRs Q6, Q7. A base voltage of TRs Q5-Q8 constituting the constant current source is set by the TR Q8 and resistors R8, R9. An offset voltage appearing output terminals OUT1, OUT2 is corrected by adjusting the resistor RV and making the current flowing to the TRs Q6, Q7 opposite to each other. For example, in selecting the resistor R3 larger than the resistor R4, if an offset voltage takes place, the slider of the resistor RV is moved toward the TR Q7 so as to increase the current flowing to the Q7 more than the current flowing to the TR Q6 and the emitter resistor of the TR Q7 is decreased.
