  • Patent number: 4485451
    Abstract: A device for the determination of the dynamic characteristics of a magnetic recording and reproducing head utilizes a support for the head to be analyzed and a standard head which are juxtaposed with common carrier and are controlled by a microcomputer through interface and shift register circuitry to automatically print out the saturation and response characteristics of the analyzed head. If a defect is determined, the standard head is activated so that the system can automatically detect whether the defect is an artifact of the recording medium or is a defect in the analyzed head.
