Definition of terms used in this Item:

"Recording media"—

All types and forms of specialized media used in recording techniques, including but not limited to tapes, drums, disks and matrices.

"Recording density" for direct recorders—

The recording bandwidth divided by the tape speed.

"Recording density" for FM recorders

The sum of the carrier frequency and the deviation divided by the tape speed.

"Packing density" for digital recorders

The number of bits per second per track divided by the tape speed.

N.B.

For the definition of the terms related to "digital computers" or "software", Items IL 1565 or 1566.

Superconductive electromagnets and solenoids, as follows---

see

(a) Those which have a non-uniform distribution of current-carrying windings, measured along the axis of symmetry when specially designed for gyrotron application, except those rated for both:

(1) Magnetic induction of less than 1 tesla; and

(2) "Overall current density" in the windings of less than 10 000 A/cm2;

(b) Those which are specially designed to be fully charged or discharged in less than

one minute, provided that:

(1) The maximum energy delivered during discharge divided by the duration of

the discharge is more than 500 kJ per minute;

(2) The inner diameter of the current-carrying windings is more than 6 cm; and (3) They are rated for magnetic induction of more than 8 tesla or "overall current

density" in the windings of more than 10 000 A/cm2.

Technical Note:

"Overall current density" is defined as the total number of ampereturns in the coil (i.e. the sum of the number of turns multiplied by the maximum current carried by each turn) divided by the total cross-section of the coil (comprising the superconducting filaments, the metallic matrix in which the superconducting filaments are embedded, the encapsulating material, any cooling channels, etc.).

Electronic devices, circuits and systems specially designed for or capable of operation at temperatures below 103K (-170°C, -274°F) and containing components manufactured from superconducting materials which perform functions such as electromagnetic sensing and amplification, current switching, frequency selection or electromagnetic energy storage at resonant frequencies above 1 MHz. These include the following—
