摘要: PURPOSE:To shorten access waiting time by selecting a head with the shortest dostance from relation between position of magnetic disk recording medium and each reading/writing data selected head. CONSTITUTION:A 1 is provided heads 3a 3b, for example, so as to be freely moved respectively, read out/ written from/to these heads. The positional 3a, 3b on are stored in current registers 11a, 11b, respectively. track which requested register 12. differences, i.e. distances, 12 found subtracters 13a, 13b. These distance inputted comparator 14 compared detected.
