ABSTRACT:
A magnetic tape drive unit constructed in a horizontal configuration to fit in a drawer or similar low profile installation, the tape being loaded and unloaded through a front slot without the need for access to the mechanism. A supply reel is inserted in the slot and placed on a supply hub, the free end of the tape being applied to a take-up reel which has a vacuum action to retain the tape. The take-up reel is mounted on an arm which swings back in the enclosure and pulls the tape over a guide and head array, the supply reel being simultaneously retracted so that the tape and reels are fully enclosed. After rewinding, the arm swings back and the supply hub is extended to the slot for removal of the tape.
