摘要：
It is disclosed that a longitudinal magnetic recording medium and apparatus has recording sections having longitudinal magnetic films (3) magnetically isolated in a recording direction. The magnetically isolated recording sections can record a single bit each so that the longitudinal magnetic recording medium can remove the irregular domain boundary of its own caused on boundaries of magnetization reversals in the recording direction. This can improve the signal-to-media noise ratio to a great extent in writing and reading.
