Abstract
The invention relates to a scanning device for a magnetic-tape apparatus, with a head disc which is rotatably mounted between an upper and a lower drum of a scanner and with head supports carrying magnetic heads, which supports are mounted at the periphery of the head disc. According to the invention, in order to simplify mounting and adjustment of the head supports, the head supports are constructed so as to allow them to be mounted on the head disc and adjusted from outside in a radial direction (R).

A scanning device for a magnetic tape apparatus,
- said scanning device comprising:
- an upper drum and a lower drum each having an outer cylindrical surface substantially parallel to an axis of rotation,
- a head disc rotatably mounted between the upper and the lower drums, said head disc having a periphery adjacent to the upper and lower drums, and being rotatable about said axis of rotation,
- and one or more head supports, each head support carrying one or more magnetic heads,
- characterized in that:
- said upper and lower drums comprise a mounting aperture in said outer cylindrical surface for receiving therethrough each of said head supports,
- wherein said head supports and head disc include means for fixing the head supports to the head disc and for adjusting the position of the head supports on the head disc, and are constructed so as to allow said head supports to be fixedly mounted and adjusted on said head disc through said mounting aperture only, without removal of the scanning device from the magnetic tape apparatus.
