ABSTRACT:
Heads of a recording/reproducing apparatus are arranged so as to face two opposite recording surfaces of a disk recording medium, individually. One of the heads is fixed to a carriage, while the other is fixed to a head arm. A leaf spring is fixed to the terminal end portion of the head arm. A metal member, weldable to the leaf spring, is embedded in a fixing portion of the carriage, which is formed of synthetic resin. The leaf spring and the metal member are fixed by welding, so that two head supporting members are fixed to each other. The heads are moved on the surfaces of the disk by a head supporting mechanism, which is a combination of the two supporting members.
