Abstract: Embodiments for changing bit rates in streaming media are provided. As portions of a streaming media file are downloaded for playback, the size of the portion is compared with an expected size determined prior to initiating playback of streaming AV data. The portion of the media file may be padded such that the size of the portion matches the size specified prior to initiating playback of streaming AV data.

Abstract: A magnetic read transducer including a magnetoresistive sensor is described, as well as a fabrication method thereof. The magnetoresistive sensor includes a cap layer overlaying a free layer. The cap layer is situated with a first thickness to absorb boron from the free layer. The magnetoresistive sensor is annealed, and boron is diffused from the free layer and absorbed by the cap layer, improving the magnetic performance of the free layer. The cap layer thickness is then reduced to a second thickness, thereby reducing the shield-to-shield (SS) stack spacing of the magnetoresistive sensor and allowing for increased areal recording density.

Abstract: A method comprises providing a magnetic element including a free layer, a pinned layer, a nonmagnetic spacer layer between the free and pinned layers, and a pinning layer adjacent the pinned layer. The free layer is biased in a first direction. The pinned layer has a first layer having a first magnetization, a second layer having a second magnetization, and a nonmagnetic layer between the first and second layer. The first magnetization is pinned parallel to a second direction substantially perpendicular to the first direction and substantially perpendicular to the ABS. The second magnetization is antiparallel to the second direction. The pinning layer is oriented along the second direction. The method further comprises providing a hard bias structure having a hard bias magnetization, initializing the hard bias magnetization along the second direction, performing at least one thermal treatment, and resetting the hard bias magnetization substantially along the first direction.

The first ferromagnetic free layer comprises a first plurality of ferromagnetic sub-layers that includes a first cobalt iron sub-layer that is in contact with the non-magnetic spacer layer, and a first amorphous cobalt boron sub-layer that is not in contact with the non-magnetic spacer layer. The second ferromagnetic free layer comprises a second plurality of ferromagnetic sub-layers that includes a second cobalt iron sub-layer that is in contact with the non-magnetic spacer layer, and a second amorphous cobalt boron sub-layer that is not in contact with the non-magnetic spacer layer.

Abstract: One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.

Abstract: One embodiment of the present invention sets forth a technique for starting playback of an audio portion of digital media content before a video portion of the digital media content is received. An advantage of the disclosed technique is that the perceived delay from the time when a user selects the digital media content to when playback of the digital media content begins is reduced. The audio may be faded-in and one or more still frames of video data may be displayed while the video stream is retrieved. Additionally, a license for DRM (Digital Rights Management) encryption of the title content may be retrieved before starting playback of the video stream, so that the digital media content that is retrieved is also protected.
