ABSTRACT:
A magneto-optic multitrack reading head which features a structure with plane layers deposited in a course of a same deposition procedure. These layers include a magnetic layer exhibiting a Kerr effect, an inter-iron gap layer and a magnetic layer for magnetic circuit closing. The magnetic layers define adjacent elementary heads, so as to be able to read multitrack media.
