Eindhoven/Jakarta – August 16, 2010 - PT IMD (Indonesia), a full line producer of optical discs, has purchased the ‘Constant Angular Velocity’ (CAV) upgrade from SINGULUS MASTERING BV. With this upgrade, the production capacity of the company’s AM Master has been increased significantly: For CD an additional output of 70 % has been reached and for DVD the production capacity almost doubled. The production capacities in CAV mode are comparable to recording speeds of 15x CD and 5R DVD in the traditional ‘Constant Linear Velocity’ (CLV) mode.
Ms. Sylvia Cendrawan, Managing Director of PT IMD, comments: “The CAV upgrade was completed with flying colors, showing excellent signals at shortened recording times per master. In terms of quality, the AM Master performs in CAV mode at a comparably high level as in CLV mode. The installation of this speed upgrade has enabled us to increase our production capacity, without the need for buying another mastering system.”
The CAV option uses a different recording method than CLV. The method refers to the constant rotation frequency of the motor in the laser beam recorder during the entire recording. This method requires a very accurate control of the laser power and the frequency of the modulated input signal for the laser, both continuously increasing during the recording.
In the traditional CLV mode, the rotation speed of the laser beam recorder motor decreases towards the outer radii, while the laser power and modulation frequency are kept at a constant value.
In CAV mode, the rotation motor rotates continuously at a fixed high frequency and the total recording time per master decreases. This significantly increases the daily production capacity of the AM Master.
Apart from the use of the ACE250 signal encoder, an important part of the CAV upgrade for the AM Master is the use of the so-called “Learning Feed Forward Control” (LFFC) module, originally developed for the CRYSTALLINE, the SINGULUS MASTERING BD platform.
LFFC allows a very fast focus control of the laser beam by learning the disc’s geometry with every revolution and using this knowledge to pre-adjust the focus for the next revolution. This is necessary to cope with the increasing linear velocities of up to 25 m/s towards the outer radii of the master, while maintaining focus.
Company Profile SINGULUS TECHNOLOGIES
SINGULUS is the only company worldwide providing the complete value chain for all optical disc formats: Mastering, Molding, Replication. Up to now, SINGULUS has delivered more than 80 Blu-ray disc production machines to customers around the world. The latest technologic developments enable additional and new applications for the Blu-ray format in the future. For this, amongst others, Blu-ray discs for the new 3D movie and television technology in HD-quality are required.
SINGULUS will considerably expand its activities in the Solar segment and intensify its market activities. Accordingly, new equipment for the photovoltaics industry will be introduced to the market. The company’s target is to position itself at the forefront for the introduction of new technologies with respect to silicon as well as thin-film solar technology. In the future, due to the available technologies, know-how and personal capabilities, SINGULUS will not only supply individual machines and equipment to the solar market but will also actively market complete systems with process know-how. The enhancement of the strategy - to become OEM supplier as well as system provider - will offer the company new and additional opportunities.
