Abstract
A method for making a magnetic recording tape, in accordance with one approach, includes coupling an underlayer to a substrate, the substrate comprising a poly ether ether ketone (PEEK). A method for making a magnetic recording tape in accordance with another approach includes coupling an underlayer to a substrate via radiation-induced grafting, the substrate comprising a poly ether ether ketone (PEEK). A recording layer may be coupled to the underlayer.
Claims18
A method for making a magnetic recording tape, the method comprising:
- forming a substrate by melt extruding and orienting poly ether ether ketone (PEEK) to align crystalline regions of the resulting substrate;
- and coupling an underlayer to the substrate, wherein a chain length of the PEEK is greater than about 20.
A method for making a magnetic recording tape, the method comprising:
- coupling an underlayer to a substrate, the substrate comprising a poly ether ether ketone (PEEK),
- wherein no adhesive is present between the underlayer and the substrate,
- wherein coupling the underlayer to the substrate includes performing radiation-induced grafting.
