  • Device for mounting magnetic head
    Patent number: 4713706
    Abstract: In this device for mounting a magnetic head, a block mounted thereto with the magnetic head is secured to a mount through magnets, so that the operations of mounting and removing the magnetic head can be easily carried out at a stroke. Furthermore, the magnets of the block and the magnets of the mount are shifted in position in a direction of setting the block aside, so that loosenesses between positioning holes formed in the block and positioning pins provided on the mount can be absorbed.
