    Abstract: An optical disk system includes a hermetically sealed optical disk cartridge (10) and a hermetically sealed optical block (12) each having overlying optical windows (14 and 16) for coupling laser light from the optical block (12) to the optical disk contained in the cartridge (10). A split spindle motor is employed with a spindle rotor magnet (44) contained in the optical disk cartridge (10) and spindle drive coils (20) disposed outside of the cartridge (10) so that the optical disk cartridge (10) needs no mechanical or electrical connections. The optical block (12) contains the optical head (68) and, in one embodiment, the seek motor (70) so as to protect the optics (64) as well as the tracking and focusing actuators (66) from contaminants.
