October – More music history #1


Diamond disks

Edison Records, which had produced only cylinder records for four decades, introduces its Diamond Disk. (*)

These 10-inch diameter, quarter-inch-thick records – with cores made from wood flour – have 150 grooves per inch. Like Edison cylinders they reproduce using a vertical stylus motion rather than lateral (side-to-side) motion. (*) (Lateral-cut will eventually become the standard.) They’re played with a long-lasting diamond stylus, at a time when most players use steel or even fiber needles that must be replaced frequently.

The heavy disks are more costly to ship, Edison players are more expensive, and the firm releases less popular music. The records don’t sell as well as the (lateral-cut) Victors and Columbias… with which they are incompatible.

Edison also introduces Blue Amberol Records (celluloid plastic … highly flammable … over a molded plaster core) in 1912. The company goes out of business in 1929.

The first Schwann LP record catalog is published by William Joseph Schwann.

An organist and trained musicologist, Schwann is owner of The Record Shop, across from MIT in Cambridge, MA. A canvass of other record-store owners encourages him to create his first catalog. The 26-page (mainly classical music) catalog, with 674 entries from 11 companies, typed by hand and mimeographed, sells 11,000 copies.

In 1953 Schwann quits the store to do the catalog full-time at 137 Newbury St. in Boston. By 1958 it lists nearly 20,000 LP’s; by the time he sells it in 1976, it lists 40,000 LPs in over 300 pages.
