Filed:

Sep 27, 1996

Appl. No.:

8/721919

Inventors:

Susan Starr Collier - Leroy NY
Michael Paul Cunningham - Rochester NY
Csaba Andras Kovacs - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B32B 300
G11B 724

US Classification:

3692751

Abstract:

A method of coating an optical recording layer on a transparent grooved substrate is disclosed. The recording layer is coated from a mixture of a primary and a secondary solvent. The solvent mixture provides a wide range of conformalities for optical recording layers.

Abstract:

A substrate is rotated at a first bead of less than or equal to 500 rpm per second. A coating composition solution is applied to the substrate at this point. The substrate is then accelerated at a first rate of between 300 and 1200 rpm per second. When the speed of the substrate reaches approximately 3000 rpm per second, a second acceleration is initiated at a second rate of greater than or equal to 3000 rpm. The coating composition is set and the substrate is decelerated. This process provides a more conformal coating of the composition providing better push-pull unwritten variability.
