laser disk
C1neutral, semi-technical
Definition
Meaning
A home video format using large (12-inch or 30 cm diameter) optical discs that are read with a laser, popular in the 1980s-1990s for movies and data storage.
Can refer to the physical medium itself or the technology/format, and is sometimes used figuratively to denote an obsolete or retro technology.
Linguistics
Semantic Notes
Almost always refers to the specific analog or digital format that preceded DVDs. The term is now largely historical, used in discussions of media history, nostalgia, or technology evolution.
Dialectal Variation
British vs American Usage

British English slightly prefers the spelling 'disc' over the US variant 'disk' for this term, though 'laserdisk' (one word) is common in both. The technology was marketed under various brand names (e.g., LaserDisc, LaserVision).
Connotations
Same connotations of obsolescence and niche retro appeal in both varieties.
Frequency
Very low frequency in contemporary usage in both dialects, limited to historical/technical contexts.

Common Pitfalls
Translation Traps (for Russian speakers)

Common Mistakes
- Misspelling as 'lazer disk'. Using 'laser disc' to refer to a CD or DVD (incorrect – those are compact discs).
