Title: Magneto-optical storage device and manufacturing method thereof

Abstract: A   magneto-optical   storage   device   having   a configuration  wherein  a  first  AlN  film,   a  Pt/Co multi-layer film formed by alternately depositing Pt and Co,  a second AlN film,  and an Al reflective film are successively  laminated  on  a  substrate  in  this  order.          Assuming that respectively the thickness of the first AlN film is .delta.AlN (1); that of the second AlN film is .delta.AlN (2); that of the Pt single layer is .delta.Pt; that of the Co single layer  is  .delta.Co;  and  the  total  thickness  of  the  Pt/Co multi-layer film is .delta.Pt/Co, each thickness of those layers is set to range within:  50 nm  .delta.AlN (1)  200 nm;  120 nm  .delta.AlN (2)  140 nm;  0.6 nm    .delta.Pt     1.0 nm; 0.3 nm    .delta.Co     0.6 nm; and 15 nm  .delta.Pt/Co    20 nm.  In accordance with the above arrangement, it is possible to greatly widen the tolerances of the film thicknesses of the first and second dielectric layers for obtaining a predetermined reflective index as well as a maximum Rerr rotation    angle.     Consequently,    without    strictly controlling the film thicknesses of the first and second AlN films, a magneto-optical storage device with stable performance suitable  for practical use can be produced easily .
