This is not scientifically accurate. The laws of physics suggest that higher coercivity reduces the risk of magnetostrictive effects on tape, except in the cases where ferric-cobalt instability arises under physical pressure. Recordable optical media such as CD-R and DVD+/-R do not use a film. They use a dye that is physical altered under tremendous heat. Reading lasers do not provide much of any heat, and they do not affect the edge of the heat mark if the dye chemistry is stable. It is the change in angle of the reflected light off the edge of the marks that provides the data. Vinyl is prone to damage, and each playing of a vinyl record causes groove deformation by the stylus. Eventually that deformation fails to recover, even from the use of the best shaped styli, and there is an increase in short wavelength distortion and a decrease in output. There is also the problem of air-born debris being embedded in the grooves in some cases that can cause permanent or semi-permanent clicks in the medium and, since the medium is analogue, in the content.
