Abstract
A method for forming a molded-in lifter for supporting a fabric liner of a flexible magnetic recording disc so that the disc is cleaned by rotation of the disc with respect to the liner when the disc is housed within a cartridge. The lifter is a raised rib that has a controlled height typically provided by deforming a molded-in rib to the desired height. The cartridge may also include a recess in the shell opposite the rib to receive the rib and prevent or reduce compression of the media if the cartridge is compressed.
