を特徴とする磁気記録再生装置。[Claims for Utility Model Registration] An audio signal is modulated into a digital signal, and the digital signal obtained by this modulation is subjected to auxiliary information indicating the characteristics of the audio signal, as well as an error correction code and interleaving processing to generate digital data. , and performs deinterleaving and error correction processing when reproducing the recorded digital data.
In a magnetic recording/reproducing device that performs the above interleaving process, deinterleaving process and/or the above error correction process using a random access memory, a data bus to which a first random access memory corresponding to the above random access memory is connected; A second random access memory connected to an address bus is provided, and the first random access memory and the second random access memory are selected by a chip select signal output from a signal processing circuit that outputs address information to the address bus. A magnetic recording/reproducing apparatus characterized in that the auxiliary information read from the magnetic tape is written to and read from the second random access memory.
