ABSTRACT:
The invention relates to a label sheet, for example in DIN A
4
format, with labels for labelling compact discs (CDs), wherein a compact disc has a read side and a rear side, and an external diameter of a readable and/or writeable region of the read side coincides with an external diameter of a region formed on the rear side, and furthermore that there are provided on the label sheet at least two annular labels for labelling the compact disc, said labels having an internal diameter and an external diameter.
BACKGROUND OF THE INVENTION
In particular since such compact discs have been used as writeable data carriers in conjunction with personal computers, it has been necessary for individual compact discs to be labelled individually as well. Already disclosed for this purpose are annular labels, for individual labelling of compact discs, in the case of which the external diameter corresponds, in practice, precisely to the external diameter of the readable or writeable region, or of the corresponding region on the rear side of the compact disc. Equally, the internal diameter of said labels is adapted to the readable region, or to the corresponding region on the rear side of the compact disc, this internal diameter exceeding said region somewhat in the radially inward direction.
It is known for compact discs to be read from and/or written to at relatively high rotational speeds in a compact-disc station. The labelling of compact discs thus has to be carried out with great care since inaccuracies may lead to an unbalance, which impairs the operation of reading from and/or writing to the compact disc or which may even damage the compact-disc station.
As far as the labelling of compact discs is concerned, various apparatuses have already been proposed.
Nevertheless, there is a need for further improving the combination of a compact disc with a label and, in particular, for specifying labels which are suitable for this purpose.
SUMMARY OF THE INVENTION
This technical problem is solved by based on the fact that the external diameter of a label is smaller than the external diameter of that region of the compact disc which corresponds to the readable region on the rear side, such that a clear projection of this region beyond the external diameter of the label of approximately 2 mm remains, and that the internal diameter of the label is adapted to a step formed on the rear side of the compact disc, such that said internal diameter exceeds a diameter dimension of the step in the radially outward direction merely by approximately 2 to 4 mm. It has been found, according to the invention, that, with substantially the same, or only negligibly reduced, overall surface area which is to have text provided on it, the writeable region can be shifted closer towards the centre. Since the regions which are located closer towards the center are less important, from the point of view of a possible unbalance, than the regions which are located further towards the outside, the displacement of the writeable region towards the inside achieves an improvement as far as sensitivity to unbalance is concerned. At the same time, a prominent compact-disc border region, which is usually shiny gold or at least silver on account of a reflection layer, remains visible even after labelling, and a compact disc labelled in this way is also easily recognized as such.
The label sheet may be provided not just in DIN A
4
format, but, for example, also in U.S. letter-size format. In this case, it is possible for the narrow side, for example, to have a dimension of 21.5 cm and for the long side to have a dimension of 27.2 cm. It is preferably provided that three labels, in particular of the same size, for labelling compact discs are prepunched on the label sheet. It is intended here for the label sheet to be of two-layered design, with a carrying substrate to which a labelling film is applied in a detachable manner. The labels are then punched out in said labelling film. If three or, optionally, more labels are provided, it is further preferred for the center points of two labels to be arranged on a straight line parallel to a longitudinal edge of the label sheet, and for the distance between the two center points to form the base side of an isosceles triangle, of which the vertex which is located over the base side coincides with the center point of the third label. Such labels are preferably printed by means of a computer-controlled printer. For this purpose, precise orientation of the labels on the label sheet is necessary for accurate printing. The given arrangement means that—when the label sheet is running through a printer in its longitudinal extent-first of all labels are located one behind the other on a line which extends parallel to a longitudinal edge of the label sheet. This results, for these two labels, in the same type of printing-head control transversely with respect to the line feed. The given arrangement means that a third label is arranged centrally, between the two labels, in the longitudinal extent of the sheet, it being the case that the arrangement of the center points on an isosceles triangle achieves an equidistant spacing between the center points in the longitudinal extent.
Advancement of the printer is also simplified as a result and, with the same type of line feed, all that is required is for the positioning of the printing head to be shifted laterally. With the relevant dimensions of the labels, optimum utilization of a DIN A
4
sheet is provided by a configuration in the case of which the center points of the three labels are arranged at the vertices of a right-angled triangle. It is also intended here, in particular, for the center points of two labels to be arranged on a straight line running parallel to a longitudinal edge of the label sheet, with the result that the right angle is defined by the connecting lines between these two center points on the straight line and the center point of the third label. A symmetrical design of the label sheet is also advantageous, it being the case that the labels are arranged symmetrically with respect to a center axis of symmetry of the sheet, in particular, with three labels, symmetrically with respect to the short center line of the label sheet, which runs transversely with respect to the longitudinal extent. This has the advantage that in the case of printer control with different introduction of a sheet with three labels in the arrangement described, all that is required is one coordinate change for the printing-head control transversely with respect to the line feed. If symmetry is provided on a label sheet with two labels arranged thereon, then it is also possible to provide, additionally or alternatively, symmetry with respect to the longitudinal center axis of symmetry of the sheet. If two-fold symmetry is provided, the labels are always printed correctly in a printer regardless of the sheet introduction. For straightforward handling of the labels, it is also provided that a contour of the label which is adapted to the internal diameter of the label has, at one location, a radially outwardly oriented, tongue-shaped section.
For drawing off the annular label, all that need then be done is to bend the label sheet in the plane in which it extends, it being possible for the tongue, which projects into the label, is formed by said section and belongs to the inner part which is to be removed, to be grasped and for said inner part to be removed. It is then also possible, in the region of this location, for the label itself to be easily removed from its carrying substrate. The arrangement of such a grip tongue or tongue-shaped recess in the region of the internal diameter also has the advantage that the tongue-shaped recess formed in this way in the label has hardly any effect as far as possible unbalance is concerned. Also contributing to this is the fact that the tongue-shaped section has a magnitude of approximately 10 to 12 mm

, with a preferred depth in relation to the internal diameter, i.e. with a radial dimension, of less than 4 mm. A furthe
