Audio Systems: Record Data, vinyl formats, vinyl grooves

Question
Hello, I am interested in physically encoded data formats of which vinyl formats of which
the vinyl record is the most historically prevalent. I have heard a vinyl records grooves could
be damaged so that a small section of music or no sound repeated itself endlessly. Can a stylus
not have this problem with records damaged in this way or is this a core flaw in vinyl record technology.

Thank you.

Answer
Sadly, it is a core flaw in the technology.
The damage could be from many sources besides a stylus. The most common would be mishandling of the disc. The disc damage could also be from a damaged stylus or inappropriate/excessive weighting on the tonearm which can degrade an entire vinyl album in little time by grinding the data off of the vinyl grooves.
This all came to pass once a format was created which required no physical contact in order to read the data (DAT and CD which are read by a laser, for instance).
Once a groove is damaged, any attempt at correcting the damage to the vinyl cannot be performed without causing loss of dynamics and data in general.
