Rotary head type recording apparatus having an erasing function based on recording mode |
摘要 |
A rotary head type recording apparatus according to the present invention can record information signals on a tape-shaped magnetic recording medium based on a plurality of kinds of recording modes in which track pitches are different from each other, and the track pitches of the recording tracks formed on the taped-shaped magnetic recording medium are varied depending on the kinds of the recording modes and at the same time a pattern of a signal-for-erasion supplied to a rotary type erasing head with wider width in the direction perpendicularly crossing a tracing direction of the head than that of a rotary type magnetic head is varied depending on the kinds of the recording modes, so that the undesirable influence of the signal-for-erasion over the recording of the information signals is reduced and at the same time power consumption is also reduced.
