Vinyl records do not break easily, but the soft material is easily scratched. Vinyl readily acquires a static charge, attracting dust that is difficult to remove completely. Dust and scratches cause audio clicks and pops. In extreme cases, they can cause the needle to skip over a series of grooves, or worse yet, cause the needle to skip backwards, creating a "locked groove" that repeats over and over. Locked grooves are not uncommon and were even heard occasionally in radio broadcasts.


Vinyl records can be warped by heat, improper storage, exposure to sunlight, or manufacturing defects such as excessively tight plastic shrinkwrap on the album cover. A small degree of warp was common, and allowing for it was part of the art of turntable and tonearm design. "Wow" (once-per-revolution pitch variation) could result from warp, or from a spindle hole that was not precisely centered. Standard practice for LPs, which were more expensive than singles, was to include the LP in a plastic lined inner cover. This, if placed within the outer cardboard cover so that the opening was entirely within the outer cover, was said to reduce ingress of dust onto the record surface. Singles, with rare exceptions, had simple paper covers with no inner cover.


There is controversy about the relative quality of CD sound and LP sound when the latter is heard under the very best conditions .


A further limitation of the record is that with a constant rotational speed, the quality of the sound may differ across the width of the record because the inner groove modulations are more compressed than those of the outer tracks. The result is that inner tracks have distortion that can be noticeable at higher vinylrecording levels.


7-inch vinyl single records were typically poorer quality for a variety of the reasons mentioned above, and in the 1970s the 12-inch vinyl single (sometimes referred to as a "doughnut"), manufactured at both 33⅓ and 45 rpm, became popular for DJ use and for fans and collectors.


Another problem arises because of the geometry of the tonearm. Master vinyl recordings are cut on a vinyl recording lathe where a sapphire stylus moves radially across the blank, suspended on a straight track and driven by a lead screw. Most turntables use a pivoting tonearm, introducing side forces and pitch and azimuth errors, and thus distortion in the playback signal. Various vinylrecording mechanisms were devised in attempts to compensate, with varying degrees of success.
