摘要：

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