The read-write characteristics of single pole type heads with a one-sided core, which have various kinds of gap lengths between the return path core and the main pole, were measured after recorded on a double-layered flexible media. The reduction in the gap length was a very effective way to improve the recording and reproducing efficiencies. However, the reproduced voltage at a high linear density depended greatly on the coercive force of the media.
