Note: A slowly flashing green LED in conjunction with the
yellow LED indicates that a prerecorded audio tape has
been inserted in the drive.
Four recognition holes allow the drive to identify the type of
tape, determine its magnetic thickness, and to determine
whether the tape is prerecorded or unrecorded or is a
cleaning cartridge. Other cartridge features that allow the
drive to optically sense cartridge in are Beginning-of-tape and
End-of-tape.
