Recording and reproducing apparatus and recording and reproducing method

摘要

A helical-scan system performs recording and reproduction on a magnetic tape by using a recording and reproducing head 5 comprising m magnetic head elements 7 (where m is 2 or larger integer). During this recording and reproduction, the following relationships are satisfied among a track width W for each of the head elements 7, a track pitch Tp between the head elements 7, and a feed amount S for a magnetic tape 6.nW/2nTp-W
