Abstract

Markings on a tape cassette label and on its tape leader cooperate with an inspection system which senses the markings to automatically compare the actual characteristics of the tape marked on the tape leader such as, for example, length and type of magnetic powder, with the characteristics described on the cassette label. In the event that the tape type and label description disagree, an alarm or removing mechanism may be automatically actuated to remove the mislabelled cassette.
