Recover magnetic
surfaces, that had damaged or that was erased (III)
Many scanning probe
microscopes can image several interactions simultaneously. The manner of using
these interactions to obtain an image is generally called a mode. The best
established types of microscopes/modes are:
STM: scanning
tunneling microscope
AFM: atomic force
microscope
MFM: magnetic force
microscope
EFM: electrostatics
force microscope
SVM: scanning voltage
microscope
KPFM: kelvin probe
force microscope
SCM: scanning
capacitance microscope
FMM: force modulation
microscope
SThM: scanning thermal
microscope
NSOM: near-field
scanning optical microscope
Advantages of the
scanning techniques are:
The resolution of the
microscopes is not limited by diffraction, but only by the size of the
probe-sample interaction volume, which can be as small as a few picometers.
The interaction can be
used to modify the sample to create small structures (Nanolithography).
Disadvantages of the
scanning techniques are:
The scanning
techniques are generally slower in acquiring images, due to the scanning
process.
The maximum image size
is generally smaller.
So we can conclude
that in paper everything is possible, can you guys imagine the effect caused by
the advertise that is done with some of this thesis that was wrote by a famous scientist
in companies or professionals that need the data recovered, how safe they can
fell ?
What a confidence that is transmitted?
Did you have experienced data loss?
The people who use
this knowledge are professionals they read and know everything that exist about
Data Recovery or that one day someone already wrote about Data Recovery and they are masters in uses
this facts to get jobs, they also say that they know things that most part of
professionals and companies do not know, and they are not saying lies because
the part that says that the majority of the professionals involved in Data Recovery do not
know this thesis and technics is true.
The most incredible part of all this is
to say or write that these techniques are commercial and that they are used for
them frequent.
Sorry but this... I
really do not believe.
