A wide tape drive for use with a wide tape holder having a frame with an open top and an open bottom non-permanently closed with a top cover and a bottom cover, releasably held together and releasably held to the frame by snap connections respectively disposed at lateral sides of the holder, the wide tape holder containing two tape hubs rotatably mounted therein proceeding substantially parallel to the lateral sides of the frame, has a base plate with two guides projecting substantially perpendicularly from the base plate which receive the wide tape holder therebetween. The drive has at least one drive motor having a drive shaft disposed between the guides, which is inserted to and engages one of the tape hubs. A magnetic read/write head is mounted on a head position assembly between the guides, and orients the read/write head relative to the tape when the wide tape holder is inserted in the tape drive. Two grippers are mounted on the guides to engage the snaps at the lateral sides of the holder as the holder is moved between the guides, thereby releasing the snaps to free the top cover and the bottom cover from the frame. Two lifer mechanisms also are respectively mounted on the guides, and respectively engage the top cover and the bottom cover after they are freed from the frame, to move these covers away from the frame, thereby producing a spacing in the drive between the top cover and the bottom cover which allows all of the magnetic tape in the wide tape holder to be wound on one of the hubs.
