GUIDELINE FOR PROTECTION AGAINST MECHANICAL STRESS
DURING DISTRIBUTION OF E-BOOKS IN CD AND DVD MEDIA

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC 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. 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 IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62780, which is a technical report, has been prepared by technical area 10: Multimedia e-
publishing and e-book technologies, of IEC technical committee 100: Audio, video and
multimedia systems and equipment.

INTRODUCTION
Some e-books are distributed by using interchangeable optical storage media such as CDs
and DVDs. Those storage media are distributed being bound in paper books/magazines or
attached to them in other appropriate manners. The media bound or included in
books/magazines are suffered from strong pressure during their distribution and/or keeping,
and sometimes become so damaged (broken or distorted) that e-book data can no longer be
read.
In order to minimize those damages of e-books during their distribution, a guideline for
protection against mechanical stress during distribution of e-books is required. Existing
standards of optical storage media specify nothing about stress-strain characteristics. The
guideline should specify how to deal with interchangeable optical storage media bound or
included in paper books/magazines. Those specifications should be based on the stress-
strain characteristics of the interchangeable optical storage media.

GUIDELINE FOR PROTECTION AGAINST MECHANICAL STRESS
DURING DISTRIBUTION OF E-BOOKS IN CD AND DVD MEDIA

1 Scope
This Technical Report provides protection schemes against mechanical stress during
distribution or keeping of e-books (see IEC 62229) stored in interchangeable optical storage
media such as CDs and DVDs, and shows the stress-strain characteristics of the
interchangeable storage media from which the protection schemes are derived.
This Technical Report supplements the information of handling multimedia e-books defined in
IEC/TS 62229.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
residual strain
permanent strain after unloading
3.2
retaining force of disk center hole
friction force between the center hole of a disk and the protrusion of the disk holder in a disk
case, to hold the disc in the disk case
Note 1 to entry: This force depends on the diameter of the center hole, the diameter of the disk holder protrusion,
material and the surface finish of the protrusion, and of the structure of the disk holder.
3.3
elastic limit
residual strain generated when stress limit is exceeded
3.4
casebound book
book consisting of a stitched book block and bound in a hard cover
