Scanning head including a magneto-optical element and scanning device including the scanning head
First Claim
1. A scanning head having a head face for scanning an information medium for reading information recorded in the information medium, which scanning head comprises a magneto-optical sensor element, and at least two magnetic flux-guiding elements, for guiding magnetic flux from the information medium being scanned through the head face to the magneto-optical sensor element, the flux guiding elements having facing planar surfaces which are spaced apart from one another to form a gap plane which extends therebetween, and the magneto-optical sensor element disposed in the gap plane which extends between the flux-guiding elements, characterized in that the two flux guiding elements border on the head face and the magneto-optical element is situated at a distance from the head face.

Abstract
Scanning head including a magneto-optical element and scanning device including the scanning head. A scanning head having a head face (1) comprises flux-guiding elements (3a, 3b) and a magneto-optical element (5). The magneto-optical element is disposed in a gap plane (4) which extends between flux-guiding elements.
