Apparatus using disc-shaped record bearing medium

DETAILED DESCRIPTION This invention is directed to the solution of the problems mentioned in the foregoing.
It is therefore a principal object of the invention to provide a novel recording and/or reproducing apparatus using a disc-shaped record bearing medium which is provided with at least one rotation indicating portion.
It is a more specific object of the invention to provide a recording and/or reproducing apparatus which is arranged to reliably mount a record bearing medium by pressing the record bearing medium on rotating driving means and to permit simplification of rotation detecting means for detecting the rotation of the record bearing medium.
Under these objects, according to preferred embodiments embodying an aspect of the present invention, an apparatus using a disc-shaped record bearing medium having an engaging portion and at least one rotation indication portion, comprises rotation means for rotating the medium, pressing means for mounting the medium on the rotation means at the engaging portion, and detection means provided on a portion of the pressing means for detecting the rotation indication portion of the medium.
These and further objects and features of the invention will become apparent from the following detailed description of preferred embodiments thereof taken in conjunction with the accompanying drawings.
