WORM Media Requirements Becausestandardread/writemediaare
incompatiblewiththeWORMfeature,aspeciallyformattedWORMtape
cartridgeisrequired.EachWORMcartridgehasaunique,worldwide
cartridgeidentifier(WWCID),whichcomprisestheuniqueCMchipserial
numberandtheuniquetapemediaserialnumber.
Data Security on WORM Media Certainbuilt‐insecuritymeasureshelp
ensurethatthedatawrittenonaWORMcartridgedoesnotbecome
compromised,forexample:
 TheformatofaWORMtapecartridgeisunlikethatofstandardread/
writemedia.ThisuniqueformatpreventsadrivethatlacksWORM‐
capablefirmwarefromwritingonaWORMtapecartridge.
 WhenthedrivesensesaWORMcartridge,thefirmwareprohibitsthe
changingoralteringofuserdataalreadywrittenonthetape.The
firmwarekeepstrackofthelastappendablepointonthetape.
LTO Cleaning Cartridges
TheLTOcleaningcartridgesarevalidfor50uses.Donotrewindandreuse
thematerialinacleaningcartridge.Reusingthematerialmayredistribute
contaminantspreviouslyremovedfromthetapepath.Ifallofthecleaning
materialisused,discardthecartridgeanduseanewcleaningcartridge.
Barcode Label Specifications for Half-Inch Media
TheSpectraLogicT50esupportsbarcodedatastringsconsistingofastart
character;from1to16characters,includingalphanumericcharactersand
anoptionalchecksumcharacter;andthestopcharacter.Quietzones
precedeandfollowthestartandstopcharacters.
Note: BlueScale12.3.1increasesthenumberofbarcodedigitstheT50e
canrecognizeto16characters.PriortoBlueScale12.3.1,the
librarycanrecognize8characters,plusonechecksumcharacter.
Symbology ThebarcodelabelingschemeusedonSpectraLogiccertified
mediausesthebarcodesymbologyofUSS‐39.Youcanobtainacomplete
