Sony has become the world's leading supplier of 3.5 inch Micro Floppydisk Drive since it first established the
3.5 inch Micro Floppydisk Drive as a new standard. Now adding the 2.0MB drive to its line-up, Sony is offering a
full line-up of 3.5 inch Micro Floppydisk Drives which are produced on a state of the art production line. High
performance is backed up by Sony’s reputation for reliability which assures OEM customers of a competitive edge.
Furthermore, Sony's innovative technology has allowed the 2.0MB drive to read and write 1.0MB disks as well.
Sony's experience in mass-
producing bulk type heads for
video tape recorders provided
the technical expertise to
develop an extremely reliable
head for the MP-F series.
Through the use of an erase gap,
Sony's bulk type head achieves
far better demagnetization and
off-track characteristics than
conventional heads.
Sony minimizes the numbers of
connectors and harnesses by
using only one PCB in the slim
line drive. The manufacture of
this board is fully automated
and uses a variety of Sony's
leading production techniques
such as surface mounting and
laser soldering.
One custom CMOS LSI is used
to control all of the functions of
the drive. This LS! contributes to
the drives low power consump-
tion, slim size, high reliability,
and reduced number of elec-
tronic parts.
The lead screw is cut on the
shaft of the stepping motor to
avoid coupling the lead screw to
the motor shaft. This unique
control method reduces stepping
motor hysterisis to virtually zero
and achieves precise and reliable
head positioning.
The center of the disk motor is
positioned with extreme accuracy
by installing the rotor on the main
chassis. The coils of the disk
motor are directly mounted on
the PCB which contributes to
the drives slimness, and through
the use of a digital servo control
mechanism, accurate rotational
speed is maintained.
All components of the drive are
laid out to take maximum advan-
tage of Sony's robot technology.
With only a single printed circuit,
board, all adjustments and
Inspections are performed using
fully automated equipment,
thereby further enhancing the
quality and reliability of Sony's
most advanced 3.5 inch floppy-
disk drives.
