Abstract
A head carriage for use in a contact-type magnetic recording/reproducing system, in particular a floppy disc system, comprises a carriage main body, a magnetic head fixedly mounted on the carriage main body and a resiliently supported arm for carrying thereon either another magnetic head for double-sided operation or a pressure pad for single-sided operation. In one aspect of the present invention, linear coefficients of expansions of various parts of the head carriage are determined so as to maintain a proper alignment between the two magnetic heads which are disposed in opposed relationship. In another aspect of the present invention, there is provided a specifically shaped pressure contact member for supporting a pressure pad to keep a desired contact condition between the magnetic head and a recording medium.
