Abstract: Embodiments of the present invention enables the trimming and writing of servo bursts in a null burst servo pattern as multiple portions in multiple passes while still demodulating each of the servo bursts as a single burst to obtain PES. Alternatively, the servo bursts can be trimmed and written using different currents in different passes respectively so that a gap can be created in the radial direction between the servo bursts. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Abstract: An electronic storage device provides rapid data availability. The rapid data availability relates to sequences of reads and writes performed by the ESD responsive to critical events, such as power-up sequences or sequences of read and/or write operations. A sequence of reads is performed upon detecting a critical event. A record of reads to be performed is maintained in a reserved area of the disk. In the case of similar but different events, such as host power-up from an off state and host power-up from a hibernation state, different read and write sequences are performed for each scenario. Improvements to the sequence of reads and/or writes may be determined, thereby enabling the ESD to improve its response to critical events over time.

Abstract: A rotatable storage media includes multiple concentric data tracks and servo sectors embedded within the tracks. In some embodiments, the servo sectors have servo burst patterns including a plurality of burst groups, with each of the burst groups including a trimmed burst that is stitched and trimmed such that is has a first width, and an untrimmed burst that has a second width that is less than the first width. In other embodiments, each of the burst groups include a pair of untrimmed bursts, with one of the untrimmed bursts being wider than the other. In still another embodiment, all bursts are trimmed, but some are wider than others. Preferably, such burst patterns are written using a two-pass-per-track servowriting scheme.

Abstract: The media player employs an operating system that supports a virtual machine into which auto-run playback programs may be loaded and run. The auto run playback program is stored on the media containing the program content, such as on an optical disc medium. When the medium is inserted in the player, the auto run playback program automatically launches and is thereafter used to access playback the media content.

Abstract: An IP telephone system includes IP telephone apparatuses and an ENUM server. The IP telephone apparatuses, connected to an IP network, perform a voice communication. The ENUM server stores NAPTR resource records containing file transfer protocols supported by the IP telephone apparatuses and returns the NAPTR resource records, responding to a query of the IP telephone apparatuses. In the IP telephone system, when receiving a voice communication instruction from a user of a source IP telephone apparatus the source IP telephone apparatus inquires the ENUM server for NAPTR resource records of a destination IP telephone apparatus. When receiving a file transfer instruction during a voice communication, the source IP telephone apparatus transfers a file to the destination IP telephone apparatus, using a file transfer protocol specified in the NAPTR resource records.

Abstract: The minor coherence-errors suffered during servowriting of bursts in a phase burst servo pattern may contribute to significant written-in runout of the resulting pattern. Embodiments of the present invention enables the servowriting of both the zig/zag bursts and/or the digital information of the phase burst pattern all in one single revolution so that the common coherence errors of the zig/zag bursts can be canceled during demodulation. Such single pass servowriting of both zig/zag bursts can be accomplished by either using additional phase-adjustment circuitry or by shifting the phase of the write clock to allow servowriting of the bursts and/or digital information all at edges of (different) integer clock cycles. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Abstract: Assemblies in accordance with the present invention can access a data storage medium having one or more disks. One such assembly comprises a mounting block including a bore and spacer, an arm stack connected with the top surface of the spacer, and a bottom arm connected with the bottom surface of the spacer.
