摘要： PURPOSE: To shorten recording time while improving a recording accuracy of a servo track by making the inertia of an external actuator smaller than that of an internal actuator to maintain a contact pressure. CONSTITUTION: An external actuator 8 has a tip part 10 in a point contact with an internal actuator 6 in substance. A drive circuit 12 energizes the external actuator 8 so that the tip part 10 of the external actuator contacts the internal actuator 6 slightly at a contact pressure. Then, the inertia of the external actuator 8 is set smaller than the inertia of the internal actuator 6. The tip part 10 of the external actuator 8 contacts one end of the internal actuator 6. But when the internal actuator 6 is driven to rotate, the tip part 10 contacts an arm supporting a head 4, for instance.

摘要： PURPOSE: To quickly perform the developing of the firmware of an MCU and to measure mechanical operations even in the case of the printed circuit board of a filing device is not exposed to the outside. CONSTITUTION: A preexisting filing device 1 transfers positional information to a developing device 2. A firmware 2a calculates a current value for moving a head based on the positional information to transmit it to the filing device 1. A VCM driving circuit 1a drives a motor based on the current value transmitted from the developing device 2 and an MCU 1b detects the present position of the head to transmit them to the developing device 2. The firmware 2a determines a next current value based on the positional information of the head and also the developing device 2 monitors the operation of a file device 6 based on the positional information of the head and forms and corrects the firmware 2a. A measuring means 6a time sequentially measures various kinds of data indicating operations of the mechanical parts of the filing device 1, a preseving means 6b preserves measured results as numerical values and a transferring means 6c transfers the measured results to an exernal device 7.

摘要： PURPOSE:To automate the designing of the controller which calculates the gains of what is called a PID regulator. CONSTITUTION:The controller to be controlled which has a transfer function enabling the double integral approximation of an input and an output, consists of an arithmetic means 2 for the gains fp, fi, and fd of the PID regulator for multiplication of P, I, and D, and a storage means 3 for a function f0 whose open loop gain is 0 dB, its phase margin theta0, and a coefficient zeta for determining the shape of an open loop characteristic. The gain arithmetic means lets omega0=2pif0 and calculates the three gains of a compensator from fp=omega0 /(K(1+ tan theta0) , fi=1/2KX(((1+zeta tan theta0) /zetatantheta)-1)X(omega0 tant heta0)/(1+tan theta0) , and fd=1/2KX(((1+zeta tan theta0) /zetatantheta)+1)X(omega0tanthet a0/(1+tan theta0) .

摘要： PURPOSE:To stably execute high speed access and to improve operation precision by controlling an actuator with an estimated speed corresponding to a selected estimated position as an accurate speed. CONSTITUTION:A digital arithmetic circuit 4 controls the actuator 3 and a head 1 is moved, whereby it is positioned in a target track on a disk 2. The arithmetic circuit 4 calculates the estimated position P1 of the head 1 and the estimated position P2 obtained by adding an offset quantity to a position signal. The estimated speed in respective positions P1 and P2 come to the same value. When discrete points exist in an observation position, they come to the different values. Consequently, the estimated speed which does not include an error can be obtained by selecting the estimated position where the discrete points are not included. When the discrete points are included in the estimated position, the estimated position where overflow does not occur in an operation process is selected, and the estimated speed in the selected estimated position is set to the accurate speed.

摘要： PURPOSE:To select a position signal with a phase not causing any error without increasing the load of the arithmetic processing section, and to demodulate the speed by providing a sampling section, a comparison section and a speed control arithmetic section to an arithmetic processing section. CONSTITUTION:A biphase position signal from a section 1 to be controlled is sampled at a 2nd period T2 shorter than a 1st period T1 by sampling sections 3-1, 3-2 for each phase. Then a difference between the preceding sample and this sample is obtained and an absolute value of the said difference of each phase is compared at a comparator section 4, and a larger difference is used to calculate the speed of the controlled section 1 at the speed control arithmetic section 5 for each of the 1st period T1. Thus, the speed of the controlled section 1 is calculated with digital processing without increasing the processing load of the speed control arithmetic section 5.

摘要： PURPOSE:To form a conversion value with high accuracy for a rear stage, by replacing the error of a digital value due to the discontinuous change of an analog signal at the maximum value or the minimum value that is the boundary value of the input range of an A/D converter by the boundary value. CONSTITUTION:A counter CNT is incremented under the constant condition of a comparator output S1, and a digital output S2 can be obtained. A digital value D from the A/D converter and the counter output S2 are read by a CPU simultaneously via a bus line B. The CPU reads the count value of the above counter at the time of starting and completing A/D conversion, and when the count value at the time of starting the conversion is different from that at the time of completing, the CPU judges that the A/D conversion of the analog signal changing discontinuously is performed. And as an A/D conversion value, the maximum value or the minimum value (that is, boundary value) of an A/D input range is adopted.
