The organization may be applied for use with optical storage.

Method of making an optical information record.

Protective overcoatings for an information storage record which includes an information-layer adapted for optical data recording.

Methods of applying protective overcoatings to an information storage record which includes an information-layer adapted for optical data recording.

The data carried in Redbook-encoded format is optically recorded onto a CD (104).

In the process, at least one optical camera (13, 14) captures the object (2) during the circulation, wherein an optical image (15, 17) is produced.

The invention applies to the preparation of thin layers for optical and/or magnetic recording.

A database is provided in the form of an optical record concerning said movement.

The optical information recording medium is good in signal quality in high-density recording.

The invention applies to the preparation of thin layers for optical and/or magnetic recording.

The invention benefits of that it is sufficient to use modulated light for obtaining optical drop registering.

A compact disc with digital data optically recorded thereon has two thickness regions.

Magnetic recording can cope with both single-track type and multiple-track type, and can prevent interference between the optical head and the magnetic head.

An optical recording medium, or the like, using such filter and performs high-density recording is also provided.

A device reads and/or records marks in a track on a record carrier via near field optical recording.
