Cover Layer Sheet for Blu-ray Discs
The Blu-ray disc is the next-generation, large capacity optical disc format. Lintec's high quality adhesive films play a vital role as components of the Blu-ray disc (single-side/single-layer type), which offers a major increase in recording capacity (27 GB), equivalent to approximately six times the capacity of current DVDs (4.7 GB).
What is Blu-ray disc?
Pre-cut Cover Layer Sheet for Uniform Thickness and High Productivity
This is a highly transparent, adhesive film with a cover layer thickness of 0.1mm. Designed for use with large-capacity Blu-ray discs, the optical film is pre-cut to match the shape of the discs. The film can be used together with Lintec's applicator for high precision application and stable production of high quality discs.
Product Features
Stable Thickness Precision
  Features extremely stable thickness precision of 2μm or less. Achieves a cover layer of high thickness precision, when compared with spin coating where the use of a liquid solvent can easily result in coating thickness differences at the inner and outer peripheries of a disc.
High Productivity
  Precut to the shape of a disc, this adhesive tape-type product is ideal for volume production of discs, and ensures high rates of productivity.
Contributes to Quality Maintenance of Discs
  The film helps maintain quality with its corrosion/erosion-resistant adhesive, and other features that include outstanding transparency, adhesion, and tracking property with respect to grooves in the recording layer. 
Laminator Developed to Maximize Layer Features
Lintec has developed a laminator that laminates the cover layer to the disc substrate with high precision. This unit offers high processing capacity (up to 15 sheets per minute), thus capitalizing on the features of pre-cut tape, while ensuring high accuracy application. It also has a unique application mechanism that prevents disc warping caused by the addition of tension during the application process, thereby facilitating the stable production of high quality discs.
