The CD-R, a recordable disc that can be played on CD and CD-ROM drives, is emerging as the ideal device forsmall-scale data distribution and pre-master editing of CD-ROMs. Several media manufacturers have plans toadd CD-R to their product line and need to become familiar with the new testing requirements. Testing ofrecordable media such as CD-R has very different aspects from the testing of CDs.The CD-R system description is given in the Orange Book, Part Two published by Sony and Philips. Since theCD-R has to be playable on a regular CD (-ROM) player it must meet both the regular Red Book specificationsfor CD and the additional requirements that allow recording on a CD-R drive.

The optical discs which can quickly record, retrieve and read enormous numbers of documents, images, music are becoming new leading products in mass media industry now. Especially CDR discs which are following the booming CD-ROM sales are becoming more and more popular. CD-R discs are compatible to CD-ROM discs, and they can record information and preserve it for long periods without changing. Because organic-dye-laid discs are relatively low cost, the application of CD-R is extending to consumer areas. In addition, we believe that in the near future CD-R duplication will replace the standard injection molding and substrate finishing process for small volume CD-ROM distribution. There are about 50 kinds of recording materials that can be used for CD-R media as summarized in Figure 1. This paper concentrates on a recording media containing a cyanine dye, because of the following features: • compatible to Orange Book Standards and available licenses through Philips (including Taiyo Yuden), • recycling of dyes can be applied and thus low costs can be achieved.

This paper reviews bismuth-substituted ion garnet films for magneto-optical (MO) recording. The influences of doped ions on anisotropy (Ku), compensation temperature (Tcomp) and coercivity (Hc) are discussed. From the viewpoint of practical application the optimum design of disk structure such as reflective layers and thickness of garnet films is also described.

Persistent spectral hole burning with multiplicity was realized at room temperature for Nile blue molecules-doped polymeric dielectric spherical microparticles based on morphology-dependent resonances. Hole parameters depending on burning conditions were studied. Dynamical characteristic behavior of hole formation was measured and analyzed with a model based on rate equations. The effective hole formation rate was obtained by simulation. Photophysical and photochemical mechanisms of the room temperature hole burning for this system was discussed.
