Roxio's separation from parent company Adaptec is now complete, the new company announced today.

Roxio started life as the digital-media subsidiary of Adaptec. Adaptec's split from Roxio allows the parent company to concentrate on developing software.

Roxio provides digital content-management software such as Toast, which personalizes and stores music, photos, video and data on CD-Rs.

Today trader The Californian-based company will start trading shares of its common stock today on the Nasdaq. A special ceremony will mark this inaugural trading at Nasdaq's New York headquarters.

Chris Gorog, Roxio's president and CEO, said: "We are extremely excited to begin trading as a profitable independent public company. Going forward, we will strive to create value for Roxio shareholders."

A conference call will take place on May 16, to discuss Roxio's fourth-quarter financial results for the year ending March 31. The conference call will be streamed live over the Web.

Roxio was taken to task by Gracenote.com last week for alleged patent and trademark infringement. The two companies will fight the case in the US courts, but Roxio's director of legal affairs last week called the accusations "unfounded".
