摘要 |
<p>Magnetic head (40) a coil (4a, 4b) of which is constituted by a first sub-pattern (6) which is provided on a substrate (9) and on which electrically conducting connection members (8) are formed and which substrate is located at one side of the magnetic head, and a film (11) on which a second sub-pattern (5) is present which is connected to the connection members (8) and is located at the opposite side of the magnetic head. The film (11) carries a further pattern which constitutes, for example, the turns of a rotary portion (42) of a transformer so that the film (11) with a plurality of magnetic heads provided thereon is suitable for use in a rotary scanning unit (43).</p> |
