linear tracking player in the shape of a musical box
just thinking: of a turntable player with configuration similar to that of a ’musical box’ and with linear tracking arm same in linear tracking player. the record can be 8" or so diameter cylindrical shape. One thing here speed is constant and may be tangential force can be lessen.
oops just in case, one record will be too bulky, problem. (and not considering yet how to make a cylindrical shape record, hahaha)
