Abstract:
Data recording/reproducing apparatus having a plurality of disk array units for recording/reproducing data, comprising:a plurality of data controlling portions for distributing input data to the disk array units; andan independent input serial transmission line and an independent output serial transmission line for inputting and outputting data between a said plurality of data controlling portions and the disk array units,wherein the input data has a predetermined length and is divided into time slots corresponding to the number of said plurality of data controlling portions, the input data being supplied to said plurality of data controlling portions with the divided time slots, said plurality of data controlling portions operating with the divided time slots, andwherein each of the disk array units comprises:a plurality of randomly accessible record mediums;record data controlling means for separating the input data received from a relevant data controlling portion through the independent input serial transmission line into record data and additional data, the record data being recorded to the randomly accessible record mediums, the additional data being data other than the record data;a central controlling portion for inputting the additional data and outputting additional data corresponding to the reproduction operation of each of the disk array units when data is reproduced from the record mediums; andreproduction data controlling means for inputting reproduction data reproduced from the record mediums and the additional data corresponding to the reproduction operation, adding the additional data corresponding to the reproduction operations to the reproduction data, and outputting the resultant data to the corresponding data controlling portion through the independent output serial transmission line.
