4-3. PREVENTIVE MAINTENANCE
4-3-1. Cleaning of Magnetic Head by Cleaning Disk
Technical Reference Manual
When you use the FDD in dusty environment, it is recommended to clean
the magnetic head surface periodically (e.g. once a month) with a
commercially available cleaning disk. Especially for a double sided
FDD, it is difficult to clean the head surface, be sure to use the
cleaning disk.
For typical usage under typical environmental condition, the cleaning
is recommended when data errors often occur.
(A) Equipment
(1) Cleaning disk
(2) SKA or user's system
(B) Cleaning procedure
(1) General method
(a) Start the spindle motor and install an appropriate cleaning disk.
Notes: 1. Do not use a damaged cleaning disk on the surface.
2. For a single sided FDD, be sure to install a single sided
cleaning disk. The cleaning surface of the disk should be in
contact with the head surface.
When the FDD is placed horizontally, the magnetic head is
located down and it faces the back side of the disk.
If a double sided cleaning disk is installed in a single sided
FDD, it may damage the head pad.
3. For a double sided FDD, a do~ble sided cleaning disk should be
used. Side 0 (lower side) and side 1 (upper side) heads are
cleaned simultaneously.
