IBM 3592 JA 18P8729 User Manual

(or re-initialize) standard JA length car-

tridges to either 60GB (to support fast

time to data) or 300GB (to support high

capacity).

The second-generation TS1120 tape

drive can initialize short length JJ car-

tridges to 60 or 100GB and initialize (or

re-initialize) standard length JA car-

tridges to 60, 100, 300 or 500GB to

support fast access to data or to help

address data growth and facilitate 

interchange. 3592 Extended Data JB

cartridges can be initialized to 140GB

for fast access to data, can be seg-

mented to 609GB or used at full

700GB capacity.

At typical compression ratios, the 3592

JB cartridge can provide usable capac-

ity of up to 1.4TB in an open system

environment and up to 2.1TB in an

IBM System z™ environment when

used with a TS1120 Tape Drive. The 

JA, JB and JJ cartridge models are

suitable for storing data that has a finite

life span and are re-writeable.

The TS1120 and 3592 J1A tape drives

are designed to work with Write Once,

Read Many (WORM) JR and JW car-

tridges to store data in a non-erasable,

non-rewriteable format. The 3592

Extended WORM JX cartridge is

designed to work with the TS1120 tape

drive only. WORM cartridges are

intended to help support the long term

retention of reference data and meet

the requirements of regulatory bodies

worldwide. The short length JR, the

standard length JW and the extended

length JX cartridges have advanced

security features that are designed to

prevent the alteration or deletion of

stored data while allowing data to be

appended to existing cartridges or files.

Special grip points and a form factor

that is similar to the IBM TotalStorage

3590 cartridge models allow the 3592

cartridges to co-exist in either an 

IBM TotalStorage Enterprise Tape

Library 3494 or a StorageTek 9310

Powderhorn Tape Library. The 

3592 cartridges can also co-exist in an

IBM System Storage TS3500 Tape

Library with IBM TotalStorage Ultrium™

LTO™ tape cartridges. This may reduce

the physical tape resources and num-

ber of cartridges needed to support the

environment and help reduce the cost

of ownership.

The IBM 3592 tape cartridge contains

an advanced fourth-generation metal

particle formulation in a dual layer coat-

ing on a half-inch-wide tape. The

IBM tape uses an advanced magnetic

coating and process designed to pro-

vide a high output and signal quality to

support the current TS1120 and 3592

J1A tape drives. The tape features an

ultra-smooth and uniform magnetic

layer less than 0.2 microns thick and a

specially refined coating formulation

designed to help improve media reliabil-

ity and performance as well as minimize

wear of the tape heads and compo-

nents. A precision timing-based servo

with enhanced features helps enable

high track densities, high data rates

and data access performance as well

as high reliability and stop-start per-

formance. In addition, modifications to

the cartridge design and construction

are designed to help improve pin reten-

tion, hub and clutch engagement, spool

alignment and tape stacking within the

cartridge. These enhancements are

designed to help improve reliability and

durability of not only the media but of

the tape drive as well.
