Claims

[Claim for Utility Model Registration] Forming a plurality of diagonal tracks on a magnetic tape, writing digital data consisting of a plurality of words onto each track, and writing in the same direction or opposite to the running direction of the magnetic tape at the time of writing. When reading the written digital data by running the magnetic tape in the same direction, the smell in each track reads the written digital data in the same direction as when the digital data was written, and the read digital data is read out. In a magnetic recording and reproducing device that writes digital data into a deinterleave memory and reads and reproduces digital data from the deinterleave memory according to address information output by a signal processing circuit, when reproducing the digital data, the traveling direction of the magnetic tape is If the direction is the same as when writing data, the signal processing circuit outputs the same address information as the read address of the deinterleave memory to access the deinterleave memory, and also accesses the deinterleave memory. When the running direction is opposite to the direction in which the digital data is written, the address information of the read address of the deinterleave memory outputted by the signal processing circuit is converted into the reverse order and outputted to the deinterleave memory. What is claimed is: 1. A magnetic recording and reproducing device comprising address information generation means for accessing.
