Final answer:
The high capacity optical disc designed for high-resolution video is a Blu-Ray disc, utilizing a blue laser for greater data storage and a polycarbonate layer for improved readability.
Step-by-step explanation:
A high capacity optical disc designed for high-resolution video is known as a Blu-Ray disc. Compared to CDs and DVDs, Blu-Ray discs use a blue laser with a shorter wavelength, specifically 405 nm, to read and write data. The pits on a Blu-Ray disc are more than twice as small as those on a DVD or CD, allowing for a significantly higher data storage capacity. This high density is essential for storing high-definition video and audio.
Blu-Ray technology utilizes a polycarbonate layer to store data nearer to the lens, enhancing readability and performance. The data layer of a Blu-Ray disc is protected by a hard coating since it is closer to the disc's surface. This advanced optical technology enables the storage of large amounts of data, such as an entire encyclopedia, on a single disc, making Blu-Ray discs a superior choice for high-definition content prior to the widespread adoption of streaming services.
