Abstract: PURPOSE: To make possible automatic discrimination by operating statistical errors of count values of random signals and obtaining output signals in radiation measurement, etc.  
     CONSTITUTION: The count value N of random signals having been calculated with a counter 1 is sent to a square-route-extraction circuit in an operator 2 to obtain a root N. This value is divided by N and the value thus obtained and the constant K of a setting circuit 22 are multiplied 24, whereby a statistical error is obtained. In a display device 3, both of the count value N and statistical error are displayed. In a setteter 4, a desired statistical error is set and this set value and the operated value are compared in a comparator 5 and an output signal is obtained under specified conditions.

Filed: 1986-01-14
Abstract: PURPOSE:To increase the track access speed by obtaining the speed information of the 2nd actuator from the relative speed between a track and a light spot and the shift speed of the 1st actuator and forming a speed feedback loop. CONSTITUTION:This track access device contains the 1st actuator 1 which moves an optical head 10 in the radius direction of a disk type recording medium 4 and the 2nd actuator 2 which moves a light spot only. The shift distance of the actuator 1 is detected by an external scale 3.

The speed of the actuator 1 is subtracted from said relative speed and therefore the speed information on the actuator 2 is obtained. Then a speed feedback loop is formed to the actuator 2. In such a way, a track access action is possible at a high speed.
