Patent ID: 7016601

Claim:
A data recording/reproducing apparatus designed to receive an input data and to generate an output data, comprising: a plurality of record media that are random-accessible, in which each of said plurality of record media is operable to store therein at least two different types of data, each type of data being stored in a respective circumferential area of the media that is radially allocated; recording and reproducing means for recording and reproducing data to and from said plurality of record media; and a plurality of input and output processing means for accessing said recording and reproducing means on time division basis, outputting said at least two different types of data that are received as input from outside the data recording/reproducing apparatus to said recording and reproducing means, and outputting the input data after processing the same, wherein each of said plurality of input and output processing means has: input means for outputting record area information and the data that is input from the outside to said reproducing and reproducing means so that the data is recorded to predetermined areas of said plurality of record media corresponding to the different types of data, and wherein said recording and reproducing means record the different types of data to the predetermined areas of said plurality of record media corresponding to the record area information that is output from said input means; wherein each of said random accessible record media is operable to store at least two different types of data thereby storing a higher quantity of data within each of said plurality of randomly accessible record media than storing only a single type of data therein.
