Abstract
A system is provided which records reproduces signals on/from a magnetic tape in a cassette in longitudinal tracks in two track patterns in two adjacent tape zones which are inscribed/read in opposite directions. The cassettes are non-reversible and comprise one imperforate main wall. Without exception the associated apparatuses comprise, as a standard feature, recording/reproducing signals in the two opposite directions without reversal of the cassette. The system may be constructed as a two-standard system suitable for use with both reversible and non-reversible cassettes in conformity with non-compatible standards on two-standard apparatuses.
