Title: Digital filter
Inventor: KUNIHIRA TADASHI
IPC: H03H17/00
Filed: 1986-10-21
Abstract: PURPOSE:To decrease the number of registers in a digital filter and the number of bits of a multiplier by setting the sample frequency of an integration term lower than that of a digital filter without varying the sample frequency of the proportional term of the digital filter for compensating a low frequency. CONSTITUTION:A cumulating unit is provided which cumulates input data stored in a 1st register (proportional term) 2 storing input data every sampling period on n-sample period basis (n: integer over 1). The cumulated result is stored in a 2nd register 12. A multiplier 5 multiplies the output from the 2nd register by a 1st factor. The multiplied result is stored in a 3rd register (integration term) 8. An adder 3 adds an output from the 3rd register 8 to an output from the 1st register 2 every sampling period. The multiplier 5 multiplies the output by a 2nd coefficient, and the fourth register 10 stores the result. Thus the sampling frequency of the integration term 8 that responds slowly is set lower than the proportional term 2 to increase the coefficient for multiplication, whereby the number of the registers and the number of bits of the multiplier can be reduced.

Title: Thin film magnetic head
Inventor: WATANABE TAKAAKI
IPC: G11B5/31
Filed: 1986-10-20
Abstract: PURPOSE:To eliminate undershoot and to solve defective waveforms and deterioration in resolving power so that higher density recording is permitted by forming magnetic poles to form a recording and reproducing gap to the magnetic characteristic lower the further from the gap. CONSTITUTION:This thin film magnetic head 1 is constituted of the two upper and lower magnetic poles 11, 12 and the recording and reproducing gap 13 formed by being sandwiched with the magnetic poles 11, 12. The magnetic poles 11, 12 are formed by dividing magnetic layers 14-16 according to the magnetic characteristic (more particularly magnetic permeability) thereof in such a manner that the magnetic permeability is lower further the gap 13. The magnetic permeability of the respective magnetic layers can be easily changed by adjusting the compound ratio of the material. The undershoot is thereby eliminated in the isolated waves and the cause for the defective waveforms and the deterioration in the resolving power is eliminated without generating unevenness in the recording and reproducing characteristics. The higher density recording is thus permitted even if no special circuits are provided.
