This Ecma Standard specifies the characteristics of a case for use with a Read-only Holographic Versatile Disc (HVD-ROM).
This Ecma Standard specifies
– the environments in which the case is to be operated and stored;
– the dimensional and mechanical characteristics of the case, so as to provide mechanical interchangeability between data processing systems.
This Ecma Standard provides for mechanical interchange between holographic disk drives.
