A tape delay cartridge device having a continuously moving closed loop of magnetic tape passing adjacent to a record head and subsequently adjacent to a playback head. A secondary loop of the tape is formed between the record head and the playback head such that there is an excess of length therebetween. This excess of length or loop provides a delay in the playback of information recorded by the record head. In this way, information being recorded can be continuously monitored, and the tape can be stopped before any bit of information reaches the playback head to delete certain portions thereof such as may be required in censoring telephone conversations or the like which are to be broadcast "live." The delay loop may be of a variable length in that the magnetic tape is wound a plurality of times around a reel prior to passing adjacent to the playback head. A flywheel is provided to stabilize the motion of the tape as it passes from the record head to the playback head through the delay reel and loop assembly. The entire magnetic tape takes the form of a closed loop, and it is wound about a storage reel which may include any variable length of the magnetic tape thereby providing a long tape and avoiding the splice problems associated with a small closed loop wherein the splice passes beneath the playback head in rapid succession.
