ABSTRACT:
A low cost and highly reliable lubricating technique is realized by using a lubricant having an average molecular weight in the range of 900 to 2500. The lubricant is efficiently supplied to inner portions of a magnetic disk apparatus utilizing heat generated during operation of the apparatus. The method of assembling the apparatus is not affected since it is not necessary to provide a separate lubricant supply mechanism.
