Data Compression   

A process that reduces the amount of storage space required 

to hold a particular block of data. Data transfer speed and total media capacity are 

affected by the data compression achieved. In accordance with industry practice, 

a typical compression ratio is 2:1 of data storage. Actual compression ratios 

achieved depend on the redundancy of data files being written.

dB   

A Decibel is a logarithmic unit of sound intensity; 10 times the logarithm of 

the ratio of the sound intensity to some reference intensity.

DC   

Direct Current

 

is the continuous flow of electricity through a conductor such 

as a wire from high to low potential.

DCM   

The Data Control Module provides the path and guides for all media 

motion inside the tape drive and to write data to and read data from the media.

Device   

According to the SCSI specification, multiple SCSI devices can be 

connected to a single SCSI bus. Each SCSI device contains a SCSI ID number that 

can be set in the range 0 to 15.

Device Driver   

A low-level (usually kernel-mode) operating system component 

that enables a PC to communicate with peripheral devices such as printers, CD-

ROMs, and tape drives. Each kind of device requires a different driver.

Differential   

A term referring to the electrical characteristics of the signal used on 

the SCSI bus interface. Differential signals minimize the effect of common mode 

signal noise and allow the SCSI bus to operate reliably over greater distances at a 

higher speed.

DLT   

Digital Linear Tape.

DLTIce   

The manufacturer’s firmware compliance management function of 

DLTSage, which provides secure archival functionality to the tape drive and tape 

cartridge.

DLTSage   

The manufacturer’s suite of preventative maintenance diagnostic 

software tools that enables users to more simply mange tape storage 

environments. 

DLZ   

Digital Lempel-Ziv 1 Algorithm is named after Abraham Lempel and Jacob 

Ziv. It is a data compression technique used in all tape drives.

E

EEC   

European Economic Community.

EEPROM   

Electronically Erasable Programmable Read-Only Memory. An 

integrated circuit memory chip that can store programs and data in a non-volatile 

state. These devices store firmware in tape drives, and can be erased and 

reprogrammed with new data.
