Imation Black Watch 9840 Specifications

Imation
Black Watch
Half-Inch Tape Cartridge
Convenient form factor based on
3480/3490E cartridges preserves
investment in existing library equipment.
Factory-written servo pattern keeps heads aligned
on data tracks for precise data reading/writing
and improved reliability.
Fast, Hardworking, Reliable
In business today, information access and capacity demands are a
growing challenge for efficient, cost-effective data management. Now,
one storage technology radically redefines performance: 9840
half-inch tape technology. The Imation Black Watch
Cartridge is at the heart of the solution, with its revolutionary, totally
internal tape path design and a familiar 3480-based form factor.
The 9840 tape cartridge draws on the long history of Imation half-inch
tape development and combines "the best of the best" from current
solutions with brand new innovations. Offering access speeds that rival
random access, the Black Watch 9840 tape cartridge sets new
standards for half-inch tape performance with proven enterprise-
strength reliability.
Speed
Access times are decreased to 12 seconds due to the dual hub,
mid-point load design. The tape rides on a cushion of air that virtually
eliminates friction between the tape and guides, enabling the fastest
search speeds of any tape storage system.

™
Performance
The 9840 is the only technology to contain a baseplate. This aluminum
baseplate enhances cartridge stability and enables precise alignment
between head and tape to ensure reliable data reading/writing.
™ 9840 Half-Inch Tape
Reliability
Advanced servo-writing techniques enable 288 data tracks to be written
across the half-inch wide tape.

DLTtape
Mid-point load dual-hub design saves time by
delivering faster access to data. Searches start from
the middle of the tape, not the end.
Metal Particulate (MP) tape
Imation backcoating dissipates static and
minimizes tape compression for optimum
performance and reliability.
With internal cartridge
never leaves the cartridge for improved
data integrity and an average access time
of 12 seconds (includes load time).
The Media Information Region (MIR)
contains directory and performance
information to optimize the management
of media and drives.
