Abstract

Magnetic tape reels 10 for data processing systems are provided with file protect rings 11. A ring 11 normally resides in groove 12 when 10 is mounted for operation on the tape machine. Groove 12 is on the back side of 10. Therefore, an operator cannot observe whether or not ring 11 is in place without removing 10 from the machine. Equally spaced holes 13, filled with a clear plastic material 14 to avoid whistling and prevent dirt from collecting, permit an operator to visually observe whether or not ring 11 is in place.
