ABSTRACT:
A cartridge comprises a housing containing a flexible record disk connected to a hub that is rotatable relative to the housing by a drive spindle. The cartridge is configured so as to be reversibly mountable on the spindle, for enabling the transducer to access and transducingly engage selectively either face of the disk through respective slots in the housing. The housing is formed of two substantially identical portions, each providing a Bernoulli surface having parts extending at equal angles in opposing divergent directions from a central part that is perpendicular to the plane of disk rotation. In an alternate configuration, the Bernoulli surface has only one part extending in a divergent direction from a remaining part that is perpendicular to the plane of disk rotation.
