Digital data recreating method for hard disk-drive in computer, involves dynamically balancing unevenness of data carrier by using plate-positioning device to effect static positioning to paper trail

摘要

The method involves sampling data in a static data carrier (1) by using a reading head carrier disk (6) rotated by the data carrier. Speed of the reading head carrier disk amounts to 500 to 2000 revolution per minutes depending on magnetization degree, data frequency and breakdown degree. An electromagnetic reading head-swiveling arm (5c) positioning unit radially retains a reading head (5a) in a paper trail. An axial unevenness of the data carrier is dynamically balanced by using a plate-positioning device to effect a static positioning to the paper trail. An independent claim is also included for a device for recreating digital data in a physically and logically no longer readable and a physically broken hard disk-drive in a computer.
