Multitrack magnetooptical read head. |
摘要 |
<p>The disclosed head is essentially comprised of a structure in planar layers deposited during one deposition process: a ultrafine magnetic layer (11), an air-gap layer (10) and a magnetic layer (9) for closing the magnetic circuit. The magnetic layers are engraved in order to define the elementary adjacent heads to read the multitrack bands.</p> |
