ABSTRACT:
A head positioning device in a disc storage system is constructed of individual flat components, particularly of ceramics which are individually ground or lapped to their final dimensions before connected with one another. Individually, the flat components comprise positioning arms, spacers and carrier arms. Head carriers are fixed to the free ends of the head positioning arms by means of pins of memory metal permitting removal of the head carriers. Read/write heads for recording and retrieving information are fixed to the removable head carriers. The carrier arms are arranged for receiving positional magnetic units. The spacers are arranged between the positioning arms and the carrier arms.
