  • Patent number: 7110210
    Abstract: A magnetic storage medium formed on a front major surface of a tape substrate defines a multiplicity of longitudinal data recording and playback tracks, each track having a nominal lateral location relative to the other tracks: and a predetermined optically manifested track servo pattern defined on the back major surface of the tape for indicating lateral displacement of the tape from a nominal lateral location of the track during tape movement across a read/write head. A magnetic tape recording and playback system employing the magnetic storage medium is also disclosed.
    Type: Grant

  • Publication number: 20050175195
    Abstract: There are techniques described to determine connectivity of a speaker. An amplifier is driven in a predefined manner. A change in power delivered to a power input of the amplifier (or an electrical apparatus in which the amplifier is incorporated) as a result of the predefined driving is sensed. A value indicative of a state of connection of one or more speakers to an output of the amplifier is determined, based on the sensed change in power.

  • Publication number: 20030194582
    Abstract: A magnetic tape comprising a substrate having on one side thereof a magnetic layer serving as a recording surface and on the other side thereof a resin layer serving as a non-recording surface, wherein said magnetic tape has a region on the side of the non-recording surface along the longitudinal direction of the tape in which a regular pattern for servo tracking having different optical properties from the other major region of the side of the non-recording surface is to be formed, and said magnetic tape has a thickness of 7 &mgr;m or less.
