Optical data storage disks |
| 摘要 |
A method of adapting the characteristics of optical data storage disks involves applying an overcoating layer to the disk in order to reduce the reflectivity and/or recording sensitivity of the disk. The overcoating layer may be a thin metal film or a thin film of an organic material, eg an absorbing dye.
