The expected number can be determined as follows:
where:
expnumlsm
expected number of scratches for each LSM.
totscracs
total number of scratches in the ACS.
totcellslsm
total number of cells in the LSM.
totcellsacs
total number of cells in the ACS.
In the previous example, the 4410 should have a range 470-530 scratches and
the 9360 a range of 70-130. To determine the BALtol range
where:
BALtol range
range of balance tolerance value.
expnumlsm
expected number of scratches for each LSM (see above).
baltol
user-supplied percent value (tolerance-value) that specifies when scratch
cartridge redistribution ends.
totscracs
total number of scratches in the ACS.
MEDia
optionally, specifies the type of cartridge to redistribute across the ACS.
Note: The SL8500 library supports only the T9x40 (9840/T9840B/T9840C and
T9940A/T9940B) media types and recording techniques.
Valid media types are:
expnumlsm = totscracs
totcellslsm
