These days, pirated copies of music albums are called illegal downloads and they can be squeezed into a mobile phone.

Mr Ronnie Loh, 71, remembers a different time. In 1978, he was a sales manager with record label Warner Music and often accompanied police officers on raids that targeted the illicit business of producing and distributing pirated music cassettes. Vinyl was on the decline and the compact disc was still a few years away.
