When
an
abnormality occurs in communications between the ID Controller and
the
host computer or a R/W Head, the ERROR indicator lights. Up to 30 files of
abnormality data are stored, and if this number is exceeded, old abnormality
data
is erased from the beginning to make room for the new data. If the Monitor
Unit
is used, apart from reading the details of these errors, it is also possible to
get the subtotals of the number of error occurrences by type.
