A compact disc in bank card or business card format
The invention relates to a compact dist in bank card or
business card format, in which on at least one side there is
formed a compact disc surface.
Such a compact disc is known from DE 296 16 619 U1. The
compact disc may be applied into usual CD-ROM drives or CD
players so that access is possible in the usual manner to
information stored on the compact disc. However the compact disc
has the disadvantage that on account of the very inhomogeneous
mass distribution on the CD carrier plate, it runs very
erratically.
It is therefore the object of the invention to further
develop a compact disc of the known type in the bank or business
card format such that the possibilities as an information
carriEr a=a not limited and in particular a malfunction-free
running in commercially available CD-RCM drives or CD players is
possible.
This object is achieved by a compact disc according to
claim 1. Advantageous formations are the subject matter of the
dependent claims.
According to the invention it is envisaged that the compact.
disc comprises a main carrier part and a break-off part, wherei;.
the compact disc surface is arranged centered on the main
carrier part and each diagonal of the main carrier part has a
length which corresponds to the diameter of the inlay deepening
of a CD-ROM drive or of a CD player.
A compact disc in bank card or business card fo~~~at has for
example the dimensions 5.4 cm X 8.4 cm, wherein the T.ain carrier
par t has dimensions of 5.4 cm x 6 c:n and the br=a~- ;ff cart
..

CA 02294800 2000-O1-04
dimensions of 5.4 cm x 2 cm. The length of each diagonal or a
main carrier part which although is still essentially
rectangular but has almost identical edge lengths is then 8 cm,
which corresponds to the diameter of the inlay deepening on the
playing plate of a CD player or of a CD-ROM drive. By way of the
improved approximation of the shape of the main carrier part to
a circular disc the running of the compact disc is less erratic.
According to a particular formation the main carrier part
and the break-off part are connected to one another via a break-
off location. With this preferably the break-off location runs
along a line perpendicular to a common side edge of the main
carrier part and the break-off part. The compact disc may then
for example also be used as an entrance ticket or theatre
ticket, since one may then invalidate the ticket with the
separation of the break-off part.
In particular for such applications it is advantageous when
on the main carrier part and/or the break-off part there are
provided integrated circuits, a computer chip, a scannable code
and/or a magnetic strip, which contain readable data which may
be acquired and read in a conventional manner, or via laser
apparatus.
In order to emphasise the impression as a business card or
bank card the length of the shorter side of the main carrier
part should correspond to the length of the longer side of the
break-off part.
The invention exploits the fact that compact discs are
played from the centre towards the outside. One may thus store
large quantities of data on the compact disc according to the
invention, which are played or may be called up in CD players
and CD-ROM drives. Also the playing of audio text, pictures,
music and likewise is possible.

In the following the invention is described in more detail
by way of the accompanying drawings. With this there is shown:
Figure 1 a plan view of a compact disc in bank card or business
card format according to the present invention;
Figure 2 the compact disc of Figure 1 with a bent-off break-off
part; and
Figure 3 the main carrier part of the compact disc in relation
to the inlay deepening of a CD player.
In Figure 1 the compact disc consists of a main carrier
part 2 on which centered there is arranged a compact disc
surface which in the usual manner comprises a central hole 5.
Furthermore provided on the main carrier part 2 is a computer
chip 4, in which additional data may be deposited and where
appropriate also processed. Via a break-off line 8 onto the main
carrier part 2 there is fastened a break-off part 3 on which
likewise a computer chip 4, a scannable code 7 and a magnet
strip 9 are arranged. The compact disc in total is essentially
rectangular and has similar dimensions to a usual bank card or
business card.
Figure 2 shows the compact disc bent off along the break-
off line 8, with which now the break-off part 3 is present
separately and where appropriate is thrown away. The infemation
which is important to the user is present on the main carrier
part 2, this part in the usual case is kept for access to the
data on the compact disc surface 1.
As Figure 3 shows the main carrier part 2 has dimensions
which permit it to be applied into the inlay deepening of a CD
player or of a CD-ROM drive. Usually such inlay deepenings have
a diameter of 8 cm, this is also the length of each of the
diagcnals of the main carrier part 2. On account of the now
almost square shape the mass distribution in the inlay deepening

with respect to the compact disc of the state of the art is much
more homogeneous so that a more uniform playing or a less
erratic running in the apparatus is made possible.
The features of, the invention disclosed in the above
description, in the drawings as well as in the claims may be
essential individually as well as in any combination for the
realisation of the invention.
