Question

The hi-def largest capacity format for optical discs is the ________ disc.

Answer 1

The hi-def largest capacity format for optical discs is the Blu-Ray disc, which uses shorter-wavelength lasers and smaller pits to store more information.

Step-by-step explanation:

The hi-def largest capacity format for optical discs is the Blu-Ray disc. Unlike CDs and DVDs, Blu-Ray discs use shorter-wavelength lasers, specifically blue laser light with a wavelength of 405 nm. The smaller and more closely packed pits on a Blu-Ray disc allow for much more information to be stored, resulting in a higher information capacity.

Answer 2

The hi-def largest capacity format for optical discs is the Blu-ray disc (BD).

Blu-ray Disc (BD) is a digital optical disc storage format designed to supersede the DVD format. It was developed by the Blu-ray Disc Association (BDA) to enable high-definition video (HD) with up to 3840x2160 resolution and high-definition audio on a single disc.

BD offers up to 50 times more capacity than a DVD, with a single-layer BD disc capable of storing 25 GB of data, and a dual-layer BD disc capable of storing 50 GB of data. Up to 128 GB of data can be stored on a quad-layer BD disc. BD discs are read with a blue laser instead of the red laser used for DVDs and CDs, which allows for smaller pits and grooves on the disc, resulting in a higher storage capacity.
