OPTICAL INFORMATION MEMORY DEVICE AND OPTICAL INFORMATION MEMORY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a high-speed/high-density optical information memory device using a one-dimensional multifunction/multiple probe array which records/ reproduces the high-density information on a disk-type recording medium by using multiple/multifunction proximity field probe techniques. SOLUTION: This device has the one-dimensionally arrayed multiple probe array and the recordable region on the disk medium is segmented to small tracks and large tacks divided by as much as the length of the multiple probe array. The movement of the multiple probe array between the small tracks and between the large tracks is performed by a double drive controller integrated with the high-resolution movement and the low-resolution movement, respectively.
