A recorded data reader is provided with a light source for emitting a beam of light and with a photosensitive means. A polarized beam splitter incorporates an interface developed between a titanium diffused region and a proton exchanged region, formed by treating one region of a titanium diffused layer for proton exchange. Both regions are arranged on a substrate of lithium niobate material. Also, a collimator lens, a surface wave electrode, and a grating lens are embedded in the same substrate, thus forming a transmitting and separating arrangement, which transmits the light beam emitted by the light source and which separates a return beam of light originating from a recording medium.

A thin film magnetic recording/reproducing head and a method of manufacturing same. The head is formed by sandwiching a multilayer thin film core between a pair of substrates, and removing a certain amount of the multilayer structure in the regions of the head which define the contact surface and the operational gap. The resulting structure has a thin film core which is thinner at the front core portion than is the back core portion. The method allows better alignment of two halves of the core portion in the vicinity of the operational gap.
