Partial Response Maximum Likelihood is a method for 

converting the weak analog signal from the head of a magnetic 

disk drive into a digital signal. Also see <Link>Advanced PRML.

Printed Wiring Assembly - Commonly known as PCB(A) for 

Printed Circuit Board (Assembly).

Q

An Application Specific Integrated Circuit (ASIC) for the tape 

drive.

R

To replace data on the hard drive with data obtained from 

another media device.

Restrictions on Hazardous Substances is an EU directive that 
restricts, and in some cases bans, the use of certain compounds in 

the manufacture of electronic equipment. RoHS mandates that 

new electrical and electronic equipment put on the market does 

not contain lead, mercury, cadmium, hexavalent chromium, 

poly-brominated biphenyls (PBB), or poly-brominated diphenyl 

ethers (PBDE).

S

Storage Area Network.

Super Digital Linear Tape.

The movement of a read/write head to a specific data track.

This is a FTP server embedded in the SDLT 600A firmware.

T

he length of time that media can be stored without losing its 

magnetic strength. For Super DLTtape II media, this period is 30 

years or more.

The International System of Units.

This command is used for site-specific commands. Compliant to 

FTP norm.

S

tatic RAM. A memory chip that requires power to hold its 

content.

T

T

he reel inside every tape drive onto which DLTtape or 

Super DLTtape media is wound. The in-the-tape drive take-up 

reel enables DLTtape and Super DLTtape systems to operate 

using a single-reel cartridge and thereby pack more media and 

data into every cartridge.
