Abstract
A data processor for properly conducting various desired diagnostics. The data processor transfers data to and from a recording medium. The data processor includes a processing circuit for performing demodulation or modulation on data having a predetermined format and a switching circuit connected to an input and an output of the processing circuit to output one of input data of the processing circuit and output data of the processing circuit. The switching circuit outputs the input data of the processing circuit when conducting various diagnostics.
Claims8
A data processor for transferring data to and from a recording medium, the data processor comprising:
- a processing circuit for performing at least one of demodulation and modulation on data having a predetermined format;
- and
- a switching circuit connected to an input and an output of the processing circuit, wherein the switching circuit outputs one of input data of the processing circuit and output data of the processing circuit.
A data processor for transferring data to and from a recording medium, the data processor comprising:
- a modulation circuit for modulating data recorded on the recording medium;
- a first switching circuit connected to an input and an output of the modulation circuit, wherein the first switching circuit outputs one of input data of the modulation circuit and output data of the modulation circuit;
- a demodulation circuit for demodulating data read from the recording medium;
- and
- a second switching circuit connected to an input and an output of the demodulation circuit, wherein the second switching circuit outputs one of input data of the demodulation circuit and output data of the demodulation circuit.
