A Blu-ray disc consists of several layers, with the primary layer being the optical disc itself made of polycarbonate plastic. It features a protective layer, a recording layer, and a reflective layer, allowing for high-density data storage. The data is encoded in pits and lands on the recording layer, and the disc typically has a capacity of 25 GB for single-layer and 50 GB for dual-layer formats. The blue-violet laser used in Blu-ray Players allows for more precise reading of these smaller data points compared to standard DVDs.
