Abstract :
Summary form only given. A recording density of 106 Gbits/in/sup 2/ has been achieved using a high-sensitivity spin-valve head and a thermally stable synthetic ferrimagnetic medium (SFM). The use of a highly stable medium allowed the demonstration to be made with a bit aspect ratio of 5.3 which is higher than the projected value. Some selected parameters are given for the demonstration.
