ABSTRACT:
A data cartridge which is edge loaded must be loaded before the access door is opened, permitting the head to enter the cartridge but entry and opening of the door can be accomplished when the head is moved vertically from a first lowered position to an upper operative position against the tape and to permit movement of the head to the upper operative position, the tape must be temporarily moved from its path in the cartridge to permit vertical movement of the magnetic head without contacting the tape. The present invention permits tape movement and head positioning upon operation of a cam shaft with a front knob.
