Abstract:
A data recording and reproducing device for recording and reproducing electrical signals onto and from a magnetic tape by means of a rotational head, said device comprising:input/output means for receiving first data from and transmitting second data to an external system;first memory means for storing the first data received through said input/output means;controller means connected to said first memory means, for controlling said device;digital signal processing means connected to said controller means, for converting the first data received from said first memory means into converted data conforming to a digital audio tape recorder format;second memory means connected to said digital signal processing means, for storing said converted data received from said digital signal processing means;recording amplifier means connected to said digital signal processing means, for amplifying the converted data received from said digital signal processing means to generate amplified data, and transmitting said amplified data to said rotational head for recording on the magnetic tape;data strobe means for receiving reproduced data from the magnetic tape and converting said reproduced data into a reproduction signal;first and second buffer means commonly connected to said data strobe means for receiving said reproduction signal from said data strobe means during both a recording mode and a reproduction mode of said device, said first and second buffer means alternately enabling transmission of said reproduction signal based on operating modes of said device comprised of said recording mode and said reproduction mode, said first buffer means enabling transmission of said reproduction signal during said recording mode, said second buffer means enabling transmission of said reproduction signal to said external system as said second data during said reproduction mode; andcomparing unit means connected to said first buffer means, for comparing said reproduction signal received from said first buffer means with said converted data stored in said second memory means during said recording mode of said device to detect data errors recorded on the magnetic tape;said controller means correcting said data errors by sequentially enabling:transmission of said first data from said first memory means to said digital signal processing means for conversion of said first data into said converted data conforming to said digital audio tape recorder format,transmission of said converted data to said recording amplifier means for generation of said amplified data, andtransmission of said amplified data to said rotational head for re-recording of said amplified data onto the magnetic tape.
