Abstract

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