发明名称 MAGNETIC RECORD MEDIA, A MAGNETIC MEMORY DEVICE AND A RECORDING METHOD ON THE SAME RECORD MEDIA, MAKING DYNAMIC COERCIVE FORCE OF A FERRO-MAGNETIC LAYER LARGER THAN OR EQUAL TO THAT OF MAGNETIC LAYER
摘要 PURPOSE: A magnetic record media, a magnetic memory device and a recording media are provided to make recorded bits have a better thermal stability, a low noise property and a better record performance. CONSTITUTION: The record media includes a base plate(21), the first seed layer(22), the second seed layer(23), a basic layer(24), a non-magnetic middle layer(25), a ferro-magnetic layer(26), a non-magnetic combination layer(28), a magnetic layer(29), a protective layer(30), and a lubricative layer(31). The layers are sequentially formed. The ferro-magnetic layer(26) is anti ferro-magnetically exchange-combined with the magnetic layer(29) via the non-magnetic layer(28). The coercive force of the ferro-magnetic layer(26) is larger than or equal to that of the magnetic layer(29).
