In reel to reel tape drives it is essential that the end of the tape be detected when leading the tape onto a take-up reel or rewinding the tape into a loading cartridge. Failure to detect the tape end accurately can damage the drive or the tape. A simple means for detecting a tape end in a reel to reel tape drive having a guiding track is provided by positioning an optical sensor at the end of the track and attaching a flag to a tape drive threading arm. When the flag is detected by the sensor, the tape drive threading arm is then in position. A simple tape end detector is shown in the figures. Drive threading arm 1 is shown with drive pin 2 in a nesting position within nesting device 6 on guiding track 3. In this position, optical sensor 4 is activated by flag 5 attached to arm 1.
