A head carriage device for use in a disk recording/reproducing unit of the type in which a head mounted on a head carriage is positionable to read or write data on a recording medium accommodated in a disk case which is placed into the unit at a recording/reproducing position thereof. The head carriage device includes an arm on which a first head is mounted, the first head being positionable on top of the recording medium, a head carriage on which a second head is mounted such that the second head is positionable on bottom of the recording medium, the first and second heads being opposed to each other and being formed such that a height of the first head above the recording medium is different from a height of the second head below the recording medium, thereby reducing a height of the disk recording/reproducing unit in which the head carriage device is installed.
