    摘要: Magnetic reference patterns may be generated on a disk or other magnetic media without the need for seed wedges. This involves writing a first magnetic reference pattern to the disk with a servo writer. The disk may then be transferred to a hard disk drive. Control circuitry within the hard disk drive may recognize the first magnetic reference pattern and then position a RW head within the hard disk drive based on the first magnetic reference pattern. As the RW drive is accurately positioned based on the first magnetic reference pattern a second magnetic reference pattern may be written to the disk using the RW head. The RW head location is determined based on the velocity and phase between the read-write head and servo setter marks contained within the first magnetic reference pattern.

    摘要: A portable electronic device comprises a device housing and a housing part arranged to overlie at least a portion of the device housing in a first position and arranged for pivoting movement away from the housing to a second position. A hinge connects the housing and the part for providing the pivoting movement of the part. An electrical connector is provided for electrically connecting at least one electrical component in the part and at least one electrical component in the housing. The electrical connector provides an electrical connection at the first and second positions of the part, but the electrical connection is broken during the pivoting movement of the part. Preferably the portable electronic device comprises a portable communication device such as a radio telephone.
