Abstract
A narrow magnetic bodyin which outward path and inward path recording magnetic head devicesWF andWR, capable of recording at least data on a metal evaporated type magnetic taperunning in the outward and inward direction and vice versa along the longitudinal direction, comprise the operation magnetic gaps GF and GR with the asymmetric structure is located at the leading side of the metal evaporated type magnetic tape. With this arrangement, magnetic field influence exerted by the narrow magnetic body can be decreased, and difference produced between magnetic recording and reproducing characteristics when the metal evaporated type magnetic tape is transported in the outward direction and in the inward direction can be decreased. Also, deteriorations of characteristics deteriorated by off-track upon reproduction can be improved. Thus, when the recording magnetic heads with the operation magnetic gaps having the asymmetric structure are in use and the metal evaporated type magnetic tape is transported in the outward and inward direction and vice versa, difference produced between magnetic recording and reproducing characteristics when the metal evaporated type magnetic tape is transported in the outward and inward direction and vice versa can be decreased. Also, deteriorations of characteristics deteriorated by off-track upon reproduction can be improved.
