A magnetic tape drive for insertion of a magnetic tape cartridge of the type having an access door pivotally mounted on a long side of the cartridge is disclosed. The cartridge is inserted through a slot in a front panel of a drawer with the long side of the cartridge parallel to the insertion direction. When the cartridge is inserted, the drawer is in an extended position and is held there by a drawer stopping mechanism. The cartridge is inserted through the slot onto the drawer as far as is permitted by a cartridge stopping mechanism. A rotatably mounted front door on the front panel of the drawer is then rotated closed and the access door of the cartridge is opened by a cam mounted on the front door in response to the rotation thereof. Cartridge and drawer release mechanisms then allow the cartridge and drawer to be fully inserted into a frame of the drive, and as the drawer and cartridge approach their operative positions in the drive, a magnetic head is moved into its operative position with respect to the cartridge in response to movement of the drawer. In addition, means for simultaneously detecting completion of insertion of the cartridge and drawer are provided.
