You'd think the music in-dustry would be howling about Personics Corp., in Redwood City, Calif., whose high-tech machines let people tape songs in record stores. Instead, some record com-panies are investing in the start-up. The secret: royalties. Personics leases the machines to stores, which charge customers 50Â¢ to $1.50 for each song they record. Musicians get a cut of the proceeds.
