Abstract

A compact disc and floppy disc compatible driver and a driving method thereof, in which a structure is improved for simultaneously driving a floppy disc and a compact disc including commodities of applying a compact disc such as a CD, CD-ROM and video CD to minimize an installation area, thereby tightly compacting a notebook computer. The driver has a magnetic head reciprocally movable along a first guide rail, a stepping motor fixedly installed to one side of the magnetic head, a turntable of a double loading system with steps rotatably attached to the upper portion of a lower side, a detecting unit installed to both inner sides of the entrance side for receiving the inserted floppy disc or compact disc, a pickup storing an optical head therein coupled to second guide rails, a sled motor fixed by being connected to the optical head for driving the optical head in the radius direction of the compact disc, and a loading mechanism for up/down a tray by two steps.

Claims2

Dependent claims

A compact disc and floppy disc compatible driver comprising:

a first guide rail installed to an inner center of one side of a main body;
a magnetic head fitted to said first guide rail to perform a reciprocating motion;
a stepping motor fixed to one side of said magnetic head while being connected to said magnetic head for driving said magnetic head along said first guide rail;
a turnable having different steps rotatably attached to an upper portion of a lower side;
a spindle motor rotatably coupled to a lower plane of said turntable;
detecting means installed to an inner rear portion of a tray for inserting a floppy disc or compact disc therein;
two second guide rails spacing from each other by a predetermined distance diagonally installed in an inner central portion;
a pickup storing an optical head therein and movably coupled to said second guide rails while running across said second guide rails;
a sled motor fixed while being connected to said optical head for driving said optical head in the radius direction of said compact disc;
and
an elastic member installed to a predetermined portion of an inner upper plane of said troy for evading an imperfect loading resulting from the different thickness of a caddy and a diskette.
