SINGLE TAKE-UP REEL, AUTOMATIC THREADING, MAGNETIC TAPE DUPLICATING APPARATUS

摘要

A magnetic tape duplicating apparatus of the type in which a recorded master tape and an unrecorded slave tape are taken up on a take-up reel with the magnetic coatings of the respective tapes in intimate contact with each other and a transfer bias magnetic field is impressed on both tapes on the take-up reel thereby to transfer a signal on the recorded master tape onto the unrecorded slave tape, wherein a device is provided for automatically engaging the master tape and the slave tape around the take-up reel at the outset of the tape winding operation, so as to enhance the efficiency of the tape duplicating operation.
