I want to know the answer to the following question:
What was the primary use of laser read discs?
All the background I'm provided with is that "Various other laser-based turntables were tried during the 1990s, but while a laser reads the groove very accurately, since it does not touch the record, the dust that vinyl attracts due to static electric charge is not mechanically pushed out of the groove, worsening sound quality in casual use compared to conventional stylus playback.". Is that enough to answer the question?
Answer: no
