There are various techniques by which facts could be recovered from magnetic media or optical media. The solutions most commonly made use of are Magnetic Power Microscopy (MFM), Scanning Probe Microscopy (SPM), Magnetic Drive Scanning Tunneling Microscopy (STM) and many others.
In these strategies a pointy magnetic suggestion is put closed into the area for being analyzed. It interacts Along with the stray magnetic subject. An image of the information is produced after which repairs are carried out on sensible hurt and so the data is recovered. Lots of corporations perform details Restoration.
