Overview
ISO/IEC 11694-1:2012 is an international standard developed by ISO and IEC that specifies the physical characteristics of optical memory cards utilizing the linear recording method. As part of the broader ISO/IEC 11694 series, this fourth edition ensures uniformity and reliability in the design and manufacture of optical memory cards, which are used for secure digital data storage and interchange.
This standard primarily addresses components such as the card’s transparent layer, optical layer, and protective layer, detailing their physical properties and material requirements. The document supports interoperability by defining compliance conditions related to dimensions, construction, and optical characteristics as linked to complementary standards.
Key Topics
-
Scope and Application
ISO/IEC 11694-1 outlines the physical design parameters for optical memory cards using linear recording, ensuring consistency in construction and material qualities across manufacturers.
-
Construction Requirements
The card’s structure follows the general framework set by ISO/IEC 11693-1. This includes material layering that enables optical data recording and retrieval via a linear x-y format.
-
Dimensions
Physical dimensions adhere strictly to those specified in ISO/IEC 11693-1, supporting compatibility with card readers and other hardware.
-
Physical Layers Detailing
- Transparent Layer: Thickness varies based on optical material choice but must meet optical path length requirements from ISO/IEC 11694-3.
- Optical Layer: Thickness and characteristics depend on recording materials and manufacturing methods, conforming to ISO/IEC 11694-3 optical standards.
- Protective Layer: Thickness is not standardized, allowing flexibility for manufacturers to tailor protection without compromising the card’s optical function.
-
Linear Recording Method
This method records data linearly in an x-y coordinate format on the optical memory card’s surface, necessitating precise physical properties to ensure data integrity and readability.
-
Compliance and Intellectual Property
Compliance may involve patented technologies or copyrighted materials, emphasizing the importance of observance of legal rights alongside technical requirements.
Applications
ISO/IEC 11694-1:2012 is critical for organizations producing or utilizing optical memory cards with linear recording methods. Typical applications include:
-
Secure Identification Cards
Government and corporate ID cards that require reliable, tamper-resistant optical data storage.
-
Access Control and Authentication
Systems needing robust, rewritable optical memory for secure access.
-
Data Storage Cards
Optical memory cards serving in data-intensive environments, supporting quick read/write operations while maintaining physical durability.
-
Interoperable Card Manufacturing
Ensures manufacturers worldwide adhere to consistent physical specifications, promoting usage interoperability among different devices and systems.
