Abstract
For a high density recording media, the magnetic switching volume is o f great importance when considering media noise and thermal stability. CoSm//Cr films have been prepared and the influence of the Cr underla yer thickness and of the magnetic layer preparation conditions on the magnetic switching volume have been investigated, through magnetic vis cosity and remnance curve measurements. The measured switching volumes ranged from 3.0 to 15.2x10(-18)cm(3), and implications regarding nois e and thermal stability are discussed.
