a voice coil motor, coupled to the enclosure, for
controlling the position of a carriage, the carriage
supporting a magnetic head, the head being positioned relative
to the disk for reading or writing magnetic information to and
from the disk;
a printed circuit board, coupled to the enclosure, for
controlling the magnetic disk drive; and
an interface cable connector, coupled to the printed
circuit board, for providing a connection from a main CPU to
the printed circuit board;
wherein said printed circuit board is disposed under the
enclosure base generally beneath said carriage and said voice
coil motor, wherein an entirety of the printed circuit board
is positioned between the spindle motor and the interface
cable connector.
Appellants' independent claim 5, reproduced below,
recites another embodiment of the instant invention:
5. A magnetic disk drive comprising an enclosure case
containing part of a spindle motor for rotating a magnetic
disk and a voice coil motor for controlling the position of a
carriage having a magnetic head for reading or writing
magnetic information from/to said magnetic disk, and a printed
circuit board having an interface cable connector attached to
the outside of said enclosure case for connection to a main
CPU, wherein said printed circuit board is disposed at a
position underneath the enclosure case opposite to said
carriage and said voice coil motor, the printed circuit board
being disposed under the voice coil motor and shortened with
respect to an area directly underneath said spindle motor, an
entirety of the printed circuit board being located between
the spindle motor and the interface cable connector, and said
interface cable connector being disposed at an end of the
printed circuit board positioned opposite to said spindle
motor.
