    Patent number: 5261065
    Abstract: With respect to input/output requests; a microprogram controls collection of data according to the data format; data accessing divides the requests for every recording medium and performs asynchronous processing; an on-line process is carried out in view of the processing priority order of the requests; parallel accessing sets requests for each medium; buffer control assures a block buffer and a page address list before receiving requests; data accessing sets a list of CCHHR codes in response to a continuous characteristic of the stored state in the recording medium; and mode deciding judges the two data transfer modes, a page search mode and a data search mode, in response to the requests.
