Apparatus for recording of an annular record carrier

In an apparatus wherein an annular record carrier is rotated in correspondence with the passage of time and an ongoing recording is made thereon, a combination comprising a housing having two sections which are relatively pivotable between an open position in which record carriers can be inserted into and removed from said housing, and a close position in which a recording is made on a record carrier located within the closed housing;

• first means in one of said housing sections for rotating the record carrier and including a rotary support for the record carrier and a spindle extending through a center opening of the latter;
• and self-centering second means turnably mounted in the other of said housing sections with freedom of play for centering itself relative to said spindle in response to movement of said housing sections towards said closed position, and for snapping in its centered position against a record carrier on said support when said housing sections move to said closed position, so that said second means rotates with said support and record carrier.
