Interchangeable Head Assembly for a Rotating Head Recorder

Shown is interchangeable head assembly 10 fastened in rotating mandrel 12 of a rotating head tape recorder. Interchangeable head assembly 10 carries magnetic heads 14 and associated electronic circuits 16.

Rotating mandrel 12, in which the interchangeable head assembly is fastened, is only half of the mandrel assembly about which magnetic tape would be helically wrapped. The other half of the mandrel is fixed mandrel 18. Rotating mandrel 12 is carried by rotating shaft 20, one end of which rotates in bearings 22, and the other end rotates in bearings 24 inside fixed mandrel 18.

Electrical connection to electronic circuits 16, which are in turn connected to heads 14, is provided through cables 26. Cables 26 pass down the hollow center of shaft 20 to a hole in the shaft where they exit the shaft. Cables 26 are connected to electronic circuits 16 via pluggable connectors 28.

To remove interchangeable head assembly 10, locking nut 30 is loosened. Locking nut 30 is used to lock rotating mandrel 12 to rotating shaft 20. With locking nut 30 loosened, rotating mandrel 12 will slide to the left along rotating shaft 20. As shown, rotating mandrel 12 has been loosened and slid along the shaft to open a space between rotating mandrel 12 and fixed mandrel 18.

With screws 32 removed, assembly 10 can then be lowered until heads 14 clear the undercut lip of mandrel 12. Connectors 28 are unplugged from electronic circuits...
