3.1

acclimatization

staging

process of conditioning material from one set of temperature/moisture conditions to another

3.2

backcoat

3.3

basefilm

base

plastic (polymer) substrate to which the magnetic layers are attached

3.4

binder

3.5

carrier

medium upon which the information is recorded

3.6

carton box

outer container that can hold one or more individual units and may be a fabrication of paper, card stock or plastic

3.7

cartridge

housing for a roll of recording material, such as photographic film or magnetic tape, wound on a single hub or reel

3.8

cassette

housing for a roll of recording material, such as photographic film or magnetic tape, whose ends are attached to two hubs or reels

3.9

cinching

tape folding back upon itself within the tape pack

3.10

conditioning

exposure of a specimen to air at a given relative humidity and temperature until equilibrium is reached

3.11

container

box, can or carton used for storage and shipping of recording materials

Note 1 to entry: Reels, cassettes, cartridges, or shells are not containers; the box into which a reel, cassette, cartridge or shell is placed is defined as a container.

3.12

copy

reproduction of the information from a master

3.13

domain

magnetic domain

cluster of the embedded magnetic particles which all align in the same north-south direction

3.14

extended-term storage conditions

storage conditions suitable for the preservation of recorded information having permanent value

3.15

flange

fixed or removable circular disc that is connected to the hub to make a reel for the purpose of protecting the roll of recording materials

3.16

flange pack

condition where the whole tape pack rests against one flange

3.17

format

dimensions of the magnetic recording and its assembly as well as the physical and magnetic specifications of the recording on the tape

3.18

heads out

configuration of magnetic tape stored on its reel or in its cassette such that the tape is positioned to play from the beginning of the recorded information

3.19

hub

cylindrical object around which the recording material is wound

3.20

hydrolysis

decomposition involving a reaction with water that results in the splitting of chemical bonds

3.21

leader

flexible plastic or paper strip which can be spliced to either end of a roll of recording material

Note 1 to entry: This practice is not recommended for extended-term storage.

3.22

leafing

multiple popped strands in a magnetic-tape wind

3.23

library wind

low-speed rewind at controlled tension to achieve a smooth tape pack

Note 1 to entry: The low speed rewind is typically 1 m/s to 3 m/s.

3.24

loose pack

undesirable pack condition in a roll of recording material, such that the outer portion of the roll can be moved and tightened by pulling on the end

3.25

magnetic field intensity

magnitude of the magnetic field, in amperes per meter, at a point in space

3.26

master

original or primary recording of the data or any version of the data

3.27

medium

media, pl

material on which information is recorded

3.28

medium-term storage conditions

storage conditions suitable for the preservation of recorded information for a minimum of 10 years

3.29

migration

transferring information from one format to another

3.30

oligomer

low molecular-weight polymer which can be produced by degradation of the magnetic tape binder

3.31

popped strand

lateral displacement of a single strand or wrap of magnetic tape extending beyond the plane of the tape pack

3.32

print-through

unintentional magnetic transfer of the recording on one layer of magnetic tape to the adjacent layers during storage on a reel/hub

3.33

reel

metal or plastic hub or core with flanges (protective sides) onto which recording material is wound

3.34

shell

outer housing of a cassette or cartridge

3.35

slot

space or slit in the winding surface of a reel or hub

3.36

splice

union of two pieces of recording or leader material to form a single piece

3.37

splicing tape

paper or plastic strip coated with a thermal or pressure-sensitive adhesive, used in splicing

3.38

spoking

deformations in a roll pack that appear radially outward and disrupt the circular nature of the wind

3.39

staging acclimatization

process of conditioning material from one set of temperature/moisture conditions to another

3.40

stepped pack

multiple adjacent strands of magnetic tape extending beyond the level of a tape pack

3.41

storage environment

conditions for storing materials, i.e. temperature, relative humidity, cleanliness of facilities and atmospheric pollutants

3.42

tails out

configuration of magnetic tape stored on its reel, or in its cassette, such that the tape must be fully rewound in order to correctly play from the beginning of the recorded information

3.43

tape pack

magnetic tape wound on a reel or hub

3.44

wind, noun

physical appearance and tension of the magnetic tape pack

3.45

wind, verb

process of transferring a roll of recording material from one spool or reel to another

3.46

window

windage hole

opening in the flanges of a tape reel
