ABSTRACT:
A carriage device of a floppy disk apparatus includes a carriage main body arranged for linear movement and a head arm extending parallel to the main body. The body and arm are formed of synthetic resin. First and second magnetic heads are respectively mounted on the main body and head arm, so as to oppose each other. Regulating members are fixed to the main body and head arm, to prevent expansion and contraction thereof. Each regulating member is made of a material having a thermal expansion coefficient and hygroscopicity lower than those of the synthetic resin.
