概要

• 論文の詳細を見る

• Double layer films of rf-sputtered amorphous GdCo have been made under different sputtering conditions. The first layer was sputtered with a dc bias voltage, and the second was successively deposited onto the first layer with non-bias. Double layer GdCo film holds as large area uniformity of magnetic properties as bias sputtered film and has good stability of bits as small as 1 μm in diameter. The films with various values of coercive force were also made by changing the ratio of thickness of these two layers. The thermomagnetic recording was carried out at a speed of 1800 rpm on this double layer GdCo disk of 150 mm in diameter.
