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. This is the origin of the phrase "like a broken record" or "like a scratched record", which is often used to describe a person or thing that continually repeats itself. To describe a company's response to a customer complaint as "Doesnbt Sound Like a Broken Record" is a compliment. Locked grooves are not uncommon and were even heard occasionally in radio broadcasts. A dusty/scratched vinyl record being played. The dust settles into the grooves. 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 was to place the LP in a paper or plastic 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. A further limitation of the gramophone record is that fidelity steadily declines as playback progresses; there is more vinyl per second available for fine reproduction of high frequencies at the large-diameter beginning of the groove than exist at the smaller-diameters close to the end of the side. At the start of a groove on an LP there are 510 mm of vinyl per second traveling past the stylus while the ending of the groove gives 200b210 mm of vinyl per second b less than half the linear resolution. Distortion towards the end of the side is likely to become more apparent as record wear increases. Another problem arises because of the geometry of the tonearm. Master recordings are cut on a 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 mechanisms were devised in attempts to compensate, with varying degrees of success. See more at phonograph. There is controversy about the relative quality of CD sound and LP sound when the latter is heard under the very best conditions (see Analog vs. digital sound argument). It is notable, however, that one technical advantage with vinyl compared to the optical CD is that if correctly handled and stored, the vinyl record will be playable for decades and possibly centuries, which is longer than some versions of the optical CD. For vinyl records to be playable for years to come, they need to be handled with care and stored properly. Guidelines for proper vinyl storage include not stacking records on top of each oth ------------------------------ End of alt.music.moxy-fruvous digest V14 #4766 **********************************************
