Motor Speed

There is a 2 minute time period marked in this section of tape for the purpose of checking the cassette tape motor speed. This portion of the diagnostic tape can be used to verify or resolve problems when a customer complains that the audio from the cassette tape sound abnormal. In some cases, improper tape motor speed can cause audio abnormalities. If the time taken for this test is between 1 minute and 56 seconds to 2 minutes and 1 second, the tape motor speed is within tolerance.
