Abstract

This article describes a process for preparing a formatted fluorinated resin-coated substrate (i.e, the substrate contains servo tracks and header information which are molded in the form of pits or grooves) by molding the pit pattern into the fluorinated resin coating. The process which makes use of a fluorinated resin coating and at the same time yields a readable formatted disk comprises the following steps. 1. Coating the substrate surface with the liquid fluorinated resin system. 2. Bringing a patterned surface containing the reverse pattern of the servo tracks and header information in contact with the liquid resin system, then curing the resin system by means of heat, light or some other energy form. 3.

3.Separating the pattern from the cured fluorinated resin to yield a formatted substrate which, when coated with an ablative media, such as Te, will ablate with low laser energy.
