3592 Tape Cartridge - memory chip

[kpovenz]

Looking for information on the memory chip that is used in the IBM 3592 tape cartridges.

The question that I have is - does the memory chip that is in the IBM 3592 tape cartridegs that store tape related data ever get reset?

I am wondering because I read that the long length durability = 300 full file passes (http://www.datasheets.pl/Magnetic_Data_Tapes/IBM_3592_TAPE_CARTRIDGE.pdf) and the highest "write pass number" I have on my tape volumes is 5. We have been using 3592JA/JB tape volumes for a number of years and I thought that this number (5) would be higher.

And if you know if the memory chip data ever gets reset do you happen to know exactly what data/information gets written/saved to the memory chip.

Thanks in advance for your help.

Have a look at the latest IBM Redbook on Tape (http://www.redbooks.ibm.com/abstracts/sg245946.html) which makes brief mention of the 3592 CM chip or Fujifilm's PDF relating to the similar LTO chip.(http://www.fujifilmusa.com/shared/bin/LTO-CM_13.56_MHz.pdf)

As far as I know the CM chip is factory-programmed with some info and then receives updates while in use, but is never reset.
