T ‐ Data Recovery Glossary 

Tagged Queuing – the drives potential to receive several I/O processes from each 

initiator. 

Task File – The set of I/O Host Interface Registers used for the transmission of 

standings, directives, and data between the host and the drive for the EIDE interface. 

Terabyte – A Terabyte = 1,099,511,627,776 bytes (or approximately one trillion 

bytes). 1,000 gigabytes or 1,000,000 megabytes are equivalent to one terabyte. 

Terminator – primarily terminators are hardware circuits or jumpers and are found 

in relation to a SCSI chain; their function is the prevention of the reflection or 

echoing of signals that spread to the end of the SCSI bus. 

Thin Client Architecture – A computer system that enables centralized data storage 

with only restricted storage capacity at the various points of use. 

Thin Film – Via a photolithographic process, a type of coating gets deposited on a flat 

surface which is used on disk platters and read/write heads, as also on the write 

element of MR heads. 

Thin‐Film Inductive Head (TFI) – a thin‐film inductive element to read and write data 

bits on the magnetic surface of the disk are made use of in a head technology. 

Time‐to‐Capacity – the next highest capacity hard drive that hits the market first. 

Time‐to‐Market – The time taken to bring a product from its conception to its 

inception in the market. Usually first‐to‐market is the desired time‐to‐market goal. 

Time‐to‐Quality – The time needed to bring a new product to market with the 

optimum level of quality and reliability. 

Time‐to‐Volume – The time frame required for the production of the product in 

suitably high volume to quench commercial needs. 

TPI (Tracks per inch) – also referred to as track density; it is the number of tracks 

written within each inch of the disk’s surfaces in order to measure how tightly the 

tracks are packed on a disk surface. 

Track – A concentric magnetic circle configuration on a disk surface used for data 

storage and reading.

Track Zero (Maintenance Track) – it is an internally stowed sound starting point on a 

hard disk for the performance of sequential seek operations on target tracks of the 

disk. 

Track‐to‐track Seek Time – The time lapse when the read/write heads transition 

from one track to the next track. 

Transfer Rate – The speed at which the hard drive transmits data from the 

controller; Processing, head switches, and seeks are all presumed into the transfer 

rate in order to precisely show drive performance. The burst mode only refers to the 

transfer of data into RAM and is hence separate from the transfer rate. 

Translating BIOS – EIDE drives larger than 528 MB are enabled access via a system 

BIOS.
