And still, the disc itself has to be labeled to be recognizable when stored outside the box. But if you purchase bulk discs on a spindle, and then buy the cases separately, there will be no inserts. Discs bought in individual cases have a card insert which can be used to describe its content, which is okay as long as the disc is stored inside the box. In the end of the 1990s recordable CDs became increasingly popular, bringing along the need for identification of the recorded content. Factory-produced CDs already had a screen-printed label on them. Originally the CD was intended for music only, but later has grown to encompass other applications, such as the storage of general data. The CD as we know it was developed by Philips in cooperation with Sony in 1982. There are music CDs, DVD or Blue-Ray discs with movies, data CDs or DVDs used for storing photos or data backups. Optical discs have already taken their place in our life. This article covers mainly labeling of optical discs as the most popular media at present. How can this be done? Of course, by labeling-either with a pen or by applying some sort of label. Once you have recorded something to a disc or tape, you will then need to distinguish it from other similar media.
