ABSTRACT:
In recording information by shifting the positions of the front edge and the rear edge of each pit on a medium stepwise from specified reference positions according to recording data, the edges of each pit are displaced stepwise with a unit of macro-step of 0.04 .mu.m, to express the data. The positions of the edges with macro-step are further adjusted to be displaced stepwise with a unit of micro-step of 256 kinds, thus suppressing the Inter Symbol Interference. With this adjustment, it is possible to reduce the influence of the Inter Symbol Interference, and hence to perform the recording with high density.
