Abstract

In the optoelecrronic industry, optical disks are considered one of the most promising technologies following optical communication. In recent years, technical development of the optical disk has been startling, with the marketing of the video disk (VD) and the digital audio disk (CD) followed by the document file and the code data disks, all of which illustrate its increasing variety. The international standards for VD and CD have been almost completed by the IEC / TC 60 (International Electrotechnical Commission, Technical Committee 60A: Sound Recording, 60B : Video Recording).¹⁾ International standardization of Optical Digital Data Disks (OD³) is being achieved by the activities in the ISO / TC 97 / SC 23 (International Organization for Standardization, Technical Committee 97 : Information Processing Systems, Sub-Committee 23: OD³).²⁾
