Explained in Details Blu-ray discs format, storage ,purpose
Blu-ray discs come in several different storage capacities and formats, each designed for specific purposes.
Here's a breakdown of the main types:
Standard Blu-ray Disc (BD)
Single-layer: Stores up to 25 GB of data.
Dual-layer: Stores up to 50 GB of data.
Blu-ray 3D (BD3D)
Single-layer: Stores up to 25 GB of data.
Dual-layer: Stores up to 50 GB of data.
4K Ultra HD Blu-ray (UHD BD)
Single-layer: Stores up to 66 GB of data.
Dual-layer: Stores up to 100 GB of data.
Blu-ray Disc Recordable (BD-R)
Single-layer: Write-once format with 25 GB capacity.
Dual-layer: Write-once format with 50 GB capacity.
Blu-ray Disc Rewritable (BD-RE)
Single-layer: Rewritable format with 25 GB capacity.
Dual-layer: Rewritable format with 50 GB capacity.
Blu-ray Disc Extended Layer (BDXL)
Triple-layer: Stores up to 100 GB of data.
Quadruple-layer: Stores up to 128 GB of data.
Each of these formats offers different storage capacities to meet various needs, from standard high-definition video to 4K Ultra HD content and large data backups
The main difference between single, double, and triple layers on Blu-ray discs lies in their storage capacity and the technology used to store the data.
Here's a breakdown:
Single-Layer (SL) Blu-ray Disc
Capacity: Up to 25 GB
Data Storage: Uses one data layer to store information. A blue-violet laser reads this layer.
Uses: Standard high-definition video and data storage needs.
Double-Layer (DL) Blu-ray Disc
Capacity: Up to 50 GB
Data Storage: Uses two data layers stacked on top of each other. The laser adjusts its focus to read each layer individually.
Uses: High-definition video and larger data storage needs.
Triple-Layer (TL) Blu-ray Disc
Capacity: Up to 100 GB (commonly used in BDXL format)
Data Storage: Uses three data layers, with the laser adjusting its focus to read each layer.
Uses: Ultra HD 4K video, extensive data storage, and archival purposes.
Quadruple-Layer (QL) Blu-ray Disc
Capacity: Up to 128 GB (commonly used in BDXL format)
Data Storage: Uses four data layers for maximum storage capacity.
Uses: Specialized high-capacity data storage needs.
Layering Technology
Laser Focus: The key to multi-layer discs is the ability of the blue-violet laser to adjust its focus to different layers without interference.
Data Density: Higher-density data storage is achieved by stacking multiple layers, allowing more information to be stored on the same physical disc space.
Each additional layer increases the storage capacity of the disc, allowing for more high-definition video content or large data files to be stored on a single disc.
