----- "Hit of The Week" were processed discs, not instantanous recordings.
They were made in a rotary "printing press", embossing the negative as an
impression in a heated pre-preg (the modern term in plastics technology, not
used then) on kraft paper base, containing a phenolic compound very much like
Condensite (Edison's Diamond Disc surface), which again is very much like the
independently developed Bakelite (TM).
----- so, unfortunately, it is not possible to consider longevity of phenolic
records as a demonstration that paper based lacquer discs also have
longevity.
Kind regards,
George
