An optical head for a recording device in which data are recorded on a recording surface of an optical memory disk, comprises, a head body which is substantially prevented from moving perpendicularly to the recording surface and is movable to be positioned roughly along the recording surface, an object lens for focussing a light beam on the recording surface, a carriage on which the object lens is mounted and which is movable to be positioned precisely along the recording surface, a drive base member for generating a force substantially parallel to the recording surface between the drive base member and the carriage to position precisely the carriage along the recording surface, and an elastic member for connecting the drive base member to the head body to support the drive base member relative to the head body elastically in a direction substantially parallel to the recording surface, joining areas between the elastic member and the drive base member and between the elastic member and the head body are aligned substantially straightly.
