摘要：A voice actuated voice logging recorder adapted to use magnetic recording tape in preloaded magazines includes a logging deck having a transport mechanism, means responsive to an input signal corresponding to voice data for enabling the transport mechanism to switch to a run position and a verification network which is activated upon insertion of a magazine into the deck. The verification network is particularly desirable to overcome limitations in the reliability of typical cassette recorders, and includes a network for rewinding the tape to ensure that all of the tape is on a rewind spool and that the tape is not bound. A second network repositions the rewound tape to enable recording onto the tape and a test recording is then produced to ensure that the tape is properly oriented, i.e., that the tape has not become twisted within the magazine. In a preferred embodiment, a second logging deck is provided, which deck may be automatically activated in the event additional detectors indicate that a faulty recording is being produced by the first deck.
