A carriage assembly for holding a pair of opposite transducers in contact with the opposite sides of a flexible disk including an arm carrying each of the transducers. A nominally flat leaf spring has the three-fold function of (1) providing a yielding connection between the two arms so that the two arms and therefore the transducers may be swung apart about this connection, (2) yieldingly holding the arms together at their places of closest approachment at which the transducers are in contact with the opposite faces of the disk and (3) providing a yielding connection between a carriage support and the arms as an assembly when in their closest approachment so that the arms and therefore the transducers may pivot with respect to the carriage with undulations out of plane of the disk. The transducers are each carried with respect to one of the arms by means of a normally flat gimbal spring which flexes to hold the transducers in proper pressure contact with the disk.
