| 摘要 | PURPOSE:To drastically shorten a data inputting and outputting time and to attain high speedification by inputting and outputting data divided into record or block units to and from plural tracks simultaneously. CONSTITUTION:A write/read operating instruction is sent from a magnetic disk processor 20 via a magnetic disk channel 21 to a magnetic disk device 10. The magnetic disk device 10 consists of a control part 11, a data buffer storage 12, a write/read head movability control part 13, a buffer storage 14i, a write/read head control part 15, a write/read head 16i and a magnetic disk medium 17i. In this case, the data divided into records or blocks are inputted and outputted to and from the plural tracks simultaneously. By this method, the data inputting and outputting time is drastically reduced and the high speedification can be contrived. | ||||||
