    • An information storage apparatus includes a disc-shaped recording medium in which control marks aligned in a predetermined rule are recorded, a head contacting or approaching a recording medium surface to reproduce/record information of the recording medium and detecting the control marks, a head driving section holding the head to move the head in a direction of coming near or away to/from a recording medium rotation center, a driving force control section controlling a driving force for head driving section, a driving time control section controlling a driving time for the head driving section using an interval of the detection of the plural control marks as a time unit, and a driving force correcting section obtaining a difference between an ideal interval based on the rule of the control marks and an actual interval of the control marks to correct the control of the driving force based on the difference.
