Technical Reference Manual
The FDD is designed to be free from periodic maintenance such as
replacement of parts, grease-up, etc. when it is operated at a normal
operation duty.
However, cleaning of the magnetic head using a cleaning disk is
recommended since it is effective to improve the reliability of the data.
If some of the parts in the FDD are operated at a specially heavy duty
condition, or if the FDD is operated over 5 years, it is recommended
to replace the wear parts according to Table 403.
