Abstract

PURPOSE:To easily return a head to an initial track position by using the number of a track where the head is present, and detecting the extent of movement of the head from the initial track position. CONSTITUTION:According to a control signal from a microcomputer, a floppy disk controller (FDC) controls the R/W circuit 51 and control circuit 52 of a floppy disk device (FDD) 5 to perform data reading, writing, etc., controlling data formats on a disk 53. ON the basis of a control signal from the FDC, the FDD5 slides a head carriage in a direction R to move an R/W head 57 from a track number ''00'' to a specified track number. The returning of the head to its origin is carried out on the basis of the extent of movement set in a track memory 58.
