Magnetic Transducer Assembly

A method is shown for assembling a multi-channel transducer consisting of a write head 10 and a read head 11, the heads consisting of individual channel heads 12 separated by shields 13.

A first sub-assembly consists of the head 10 and the second consists of the head 11. Each is assembled by placing the shields 13 in slots of a fixture 14 where they are held in place by tongues 15.

The two parts of each fixture 14 are held together by dowels.

Pole pieces 16 are placed between shields on one side of the tongue 15 and pole pieces 17 with coil 18 are placed between shields on the other side of the tongue thus effecting accurate alignment of pole pieces 16 and 17.

Frame components 19, 20, 21, 22 are inserted into the fixtures 14 and are bolted together by dowels 23. The entire unit is cured, solidifying the epoxy resin with which all the parts are coated and forming the entire assembly into one solid mass.

After curing, the tongues 15 are removed, freeing the head assembly from the fixtures 14. The shield assemblies are then cut between points 24, 25 and at points 26 and 27 to separate the assembly at the air gap planes 28 and 29 and expose the pole faces.

The pole faces are lapped to align the pole tips and finally the three separate parts left, right and middle are bolted back together by dowels 23.
