Magnetic head with magnetic coil

Magnetic head with magnetic coil

A magnetic head suitable for use in a magneto-optical apparatus. The magnetic head has a flat electromagnetic coil (1) with a central opening (3). The coil has parallel coil layers (5a, 5b), each of the coil layers having a turn (5A, 5B) arranged around the central opening. At least one of the coil...

description A magnetic head suitable for use in a magneto-optical apparatus. The magnetic head has a flat electromagnetic coil (1) with a central opening (3). The coil has parallel coil layers (5a, 5b), each of the coil layers having a turn (5A, 5B) arranged around the central opening. At least one of the coil layers has turns of which the turns closer to the central opening have smaller widths (w) than the turns further away from the central opening. At least one of the coil layers has an outermost turn (5Bo) situated closer to the central opening than the outermost turn (5Ao) of one of the other coil layers. The defined coil structure has a limited capacitance while the power dissipation is also limited.
