Abstract:
A continuous method of manufacturing a magnetic disk comprising the steps of (1) coating a smooth surface of a temporary substrate, such as Mylar, with a magnetic coating; (2) overcoating the magnetic coating with an adhesive coating, the combination of the magnetic coating and the adhesive overcoating comprising a transfer coating; (3) placing at least the first surface of a disk-shaped substrate, such as an aluminum substrate, into contact with the transfer coating; (4) applying sufficient pressure between the first surface and the transfer coating to cause the transfer coating to adhere to the first surface, the adherence of the transfer coating to the first surface being greater than to the temporary substrate, and (5) removing the temporary substrate. Both sides of the disk-shaped substrate can be coated at the same time in a preferred embodiment utilizing as the adhesive either a thermoplastic or thermosetting material.
