Patent number: 11393504Abstract: A magnetic tape device includes: a magnetic head; a head actuator that holds the magnetic head; and a tape lifting mechanism including a lifter arm. The lifter arm comes into contact with the magnetic tape to separate a magnetic tape from the magnetic head. The tape lifting mechanism moves the lifter arm in a push-out direction in conjunction with the head actuator moving in a first direction. The tape lifting mechanism moves the lifter arm in a retreating direction in conjunction with the head actuator moving in a second direction. The lifter arm pushes out the magnetic tape to separate the magnetic tape from the magnetic head, in response to the lifter arm moving in the push-out direction. The lifter arm separates from the magnetic tape to bring the magnetic tape into contact with the magnetic head, in response to the lifter arm moving in the retreating direction.Type: GrantFiled: December 25, 2017Date of Patent: July 19, 2022Assignee: NEC Platforms, Ltd.Inventor: Kenichi Ojima
