Title:
PRODUCTION OF MAGNETIC RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPH08239498
Kind Code:
A
Abstract:

To produce a magnetic recording medium while minimizing electrostatic charge buildup on the medium during production by smoothing a wet coating on a moving web surface with a flexible blade having two major surfaces and contg. a conductive layer.

A web 10 moves in a coating apparatus, and a liq. coating material is applied to a surface of the moving web to form a wet coating 14. The wet coating 14 of the coated web is smoothed with a smoothing apparatus 20, which contains a flexible smoothing blade 22 holded at a certain position by a blade clamp 24. The blade 22 has two major surfaces, contains a conductive layer, and is positioned so that a portion of one major surface is in contact with the wet coating 14 so that electrostatic charge on the coated web is dissipated. Thus, a magnetic recording medium can be produced while minimizing electrostatic charge buildup during production.
