Descriptions
This paper describes the recording characteristics, including the performances of recording density and over-write erase ratio, in unsaturated digital magnetic recording. The effects of the medium thickness δ and the gap length gw of a write head are particularly noticed. The experimental results can be summarized as follows : (1) In general, half amplitude density D_<50> increases with decreasing write level K
