History:
Pre JTC 1:
SC 23 was established by ISO/TC 97 at its 12th Plenary Meeting held in Stockholm, Sweden in 1984. The Secretariat was assigned to JISC, Japan. The initial title was “Optical Digital Data Disk” and the area of work was “Standardization of optical digital data disk for media and data interchanged between information processing systems. The Chairman appointed was Dr. Junichi Shimada (JP) and the Secretary was Mr. Takeo Misao from JSA, JISC.
ISO/TC 97/SC 23 had the following three plenary meetings:
– 1st Plenary: 1985-05, Tokyo, Japan
– 2nd Plenary: 1986-09-22/25, Geneva, Switzerland
– 3rd Plenary: 1987-10-13/16, Washington DC, USA
The sub-group structure was as follows:
– Clamping Method ad hoc group (Convenor: Mr. Mike Deese, ISA)
– Editorial Group for case Dimensions and Drawings
– Special Working Group on DP 9171-3 and 4 (Convenor: Dr. J.A. T. Veroeven, Netherlands)
– Editing ad hoc group on Terminology
During this period, SC 23 concentrated on its first project, standardization of 130 mm Write-Once Optical Disk Cartridges.
1987
