ABSTRACT:
A helical scan type magnetic recording and/or reproducing apparatus comprises a rotary erase head mounted on a rotary drum at such a position that in a normal recording mode the rotary erase head does not erase a portion of a track formed on a magnetic tape by a rotary recording and/or reproducing head which leads the rotary erase head and in a long-time recording mode the rotary erase head erases an overlapping portion of two mutually adjacent tracks formed by a pair of rotary recording and/or reproducing heads respectively leading and lagging the rotary erase head.
