Overview
EN 61120-5:1995 is an international standard developed by the International Electrotechnical Commission (IEC) and adopted by the European Committee for Electrotechnical Standardization (CLC). It specifies the requirements for reels used in professional digital audio tape recorder reel-to-reel systems utilizing 6.3 mm magnetic tape. This standard is part 5 of the EN 61120 series and focuses exclusively on the mechanical and dimensional specifications for reels, ensuring compatibility and interoperability within professional audio recording environments.
This standard applies to reels designed for use in digital audio tape recorder systems that enable high-quality sound recording and playback in professional studio settings and broadcasting. It supports the international unification of reel design, enhancing program exchange and equipment interchangeability across manufacturers and regions.
Key Topics
Scope of Application
EN 61120-5 outlines the requirements for reels compatible with digital audio tape recorders using 6.3 mm magnetic tape. It ensures reels meet professional use criteria, primarily targeting sound recording and reproducing systems.Reel Types and Center Holes
The standard specifies two types of reels based on center-hole diameter:- Reels with an 8 mm center hole
- Reels with a 76 mm center hole
These variations accommodate different machine designs and user preferences within professional environments.
Mechanical Requirements and Dimensions
The standard provides detailed mechanical and dimensional requirements, such as:- Diameter and width measurements
- Symmetrical design to allow mounting from either side
- Limitations on flange curvature, ribbing, or raised designs to ensure smooth operation
- Maximum moment of inertia values related to reel size for mechanical stability and tape tension management
Construction and Design Notes
Reels must ensure the tape width of 12.2 mm is accommodated within the specified diameter, with allowances for flange designs that do not extend beyond certain limits to avoid interference or tape damage.Normative References
EN 61120-5 builds upon other relevant IEC standards, including those covering magnetic tape properties and reel-to-reel mechanical systems, reinforcing a cohesive framework for digital audio tape recording systems.
Applications
EN 61120-5 is essential for manufacturers and users of professional digital audio recording equipment. Its applications include:
Broadcasting and Studio Recording
Enables reliable, high-fidelity sound recording and playback by specifying standard reels that ensure consistent tape handling across equipment.Program Exchange
Facilitates international interchange of prerecorded tapes by standardizing reel dimensions, minimizing compatibility issues between different recording systems.Equipment Manufacturing
Provides manufacturers with precise technical criteria for producing reels that fit seamlessly into 6.3 mm professional reel-to-reel digital audio tape recorders.Archiving and Preservation
Assists archives and libraries in preserving digital audio content on standardized reels, ensuring longevity and compatibility with playback systems.

FOREWORD
The IEC (International Electrotechnical Commission) is a worldwide organization for standardization
1)
comprising all national electrotechnical committees (IEC National Committees). The object of the IEC is to
promote international cooperation on all questions concerning standardization in the electrical and
electronic fields. To this end and in addition to other activities, the IEC publishes International Standards.
Their preparation is entrusted to technical committees; any lEC National Committee interested in
the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
collaborates closely with the International Organization for Standardization (ISO) in accordance with
conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
3) They have the form of recommendations for international use published in the form of standards, technical
reports or guides and they are accepted by the National Committees in that sense.
In order to promote international unification, IEC National Committees undertake to apply IEC International
4)
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
International Standard IEC 1120-5 has been prepared by sub-committee 60A: Sound
recording, of IEC technical committee 60: Recording.
The text of this standard is based on the following documents:
