ABSTRACT:
The end of an auto-loading magnetic tape for a computer magnetic tape device is formed in a loop with the magnetized side thereof bent to face outwardly. The length of the bent portion is equivalent to between half and twice the square root value of the product of the radius of a file reel and the spare radial length of the reel radius. The loop is so constructed that the extreme end of the magnetic tape is bonded to the base side of the magnetic tape. The end of the magnetic tape thus offers higher air resistance than the other parts of the tape to the air flow in the cartridge containing the magnetic tape, thereby enhancing the chance of success in a tape auto-loading operation.
