ABSTRACT:
Thin film disk media which is initially coated with lubricant from the ID or normal head landing area radially outwardly across the data zone. The initially applied lubricant area is thinned and buffed in the data area so as to provide a substantially reduced lubricant layer overlying the data zone characterized by markedly improved coefficient of friction characteristics in relation to what would have been produced without such lubricant removal and buffing.
