In Recording Indus. Ass’n of Am. v. Diamond Multimedia Sys., Inc., 180 F.3d 1072, 51 U.S.P.Q.2d (BNA) 1115 (9th Cir. 1999), the Ninth Circuit applied the Audio Home Recording Act to the Rio digital audio player,[1] concluding that the Rio was not a digital audio recording device under that statute.
The ruling also affirmed that Space shifting the digital files from a PC's hard disk to the Rio falls under personal use. The ruling reads "Such copying is paradigmatic noncommercial personal use entirely consistent with the purposes of the Act." ( 17 U.S.C. § 1008).
