DNV 423 PDF

This Standard specifies the physical, optical and mechanical characteristics of a Holographic Data Storage Disk (HDSD) that employs holographic recording to enable data interchange between disks.

The 120 mm diameter holographic disk has a nominal capacity of 1 Tbyte.

This Standard specifies

- the conformance of recording disk, testing and the reference drive;

- the environments in which the disks are to be operated and stored;

- the mechanical, physical and dimensional characteristics of the disk;

- the format of embossed track information and user data information to be recorded on a disk;

- the holographic recording characteristics of the disk to enable data processing systems to record and read data on or from the disk;

- the minimum quality of user-recorded data on the disk, enabling data processing systems to read data from the disk.
