<P>PROBLEM TO BE SOLVED: To quantitatively and highly precisely execute the quality discrimination of a motor control circuit which performs feed back control based on analog information fed back from a motor to be controlled. <P>SOLUTION: The data of the control signal judging profile 12 of a normal recording control part 100 are compared with the data of the control signal profile 13 of the recording control part 100 to be inspected when the feed back control is executed by the feed back signal (input signal profile 11) which is the same feed back signal when the control signal judging profile 12 is obtained. Whether the drive voltage waveforms of a PF motor 58 and a CR motor 63 relative to the feed back control are judged normal or not, based on the result whether both data are matched or not, thereby judging whether the recording control part 100 to be inspected is normal or not. <P>COPYRIGHT: (C)2008,JPO&INPIT |
