Therefore, the two bonded plates have no or little vacuumed clearance at the bonded parts thereof. As a result, heat transfer in the surfaces thereof is uniform, and the intermediate dielectric plate 4A that contacts the O-ring 35 can have a temperature of lower than 200 DEG C in the interior side thereof so that the O-ring can be prevented from thermal changes. A vacuum treatment with high interior uniformity can be accomplished.

Title: Rewritable optical information medium
Inventor: ZHOU GUO-FU
IPC: G11B7/2437
Filed: 1999-06-10
Granted: 2002-02-21
Abstract: A description is given of a disc-shaped rewritable optical information medium having an IPIM stack (2) comprising a phase-change recording layer (4) sandwiched between two dielectric layers (3,5), and a metal mirror layer (6). The thickness of the recording layer (4) increases gradually with increasing radius r. As a result, the complete erasure time CET of recorded marks decreases from the inner radius ri to the outer radius ro. Therefore, at a point closer to the outer radius marks can be recorded at a higher linear speed than at a point closer to the inner radius. This effect ensures that the recording medium can be used for recording at a constant angular velocity (CAV).
