HIGH SPEED POSITION DECIDING METHOD OF MINI DISK

摘要

storing corresponding cluster and track number in corresponding address and tracks index table of each cluster group and determining wheter read address is target location after reading current address (S1); terminating a positioning system in case of target location and determining whether the different of current location and target location is less than 1 cluster (S2); determining whether the difference is positive value if the address difference is less than 1 cluster and returning to the initial step (S1) again (S3); obtaining difference of distance between target track and current track after searching track number in case the address difference is greater than 1 cluster (S4); determining whether the difference of distance obtained from the step 4(S4) is greater than 5 tracks in case the difference of distance is not positive (S5); initializing after positioning with the difference of track in case the difference of distance is greater than 5 tracks (S6); positioning with the difference of track from target location by calculating track number after searching cluster data per track in the index table if the difference of distance is less than 5 tracks.
