  • Patent number: 4455641
    Abstract: In a linear tone arm tracking system for a record player where the stylus tone arm moves on a guiderail across a recording, eg. a record disc on a turntable, an improvement is provided in which the stylus tone arm is connected to a partial sleeve, which sleeve hovers partially over the guiderail and means, such as air pressure means, causes the partial sleeve to hover over the guiderail in proximity therewith, so that when the stylus rides in the record groove and is laterally shifted thereby, the tone arm and partial sleeve readily shift over the guiderail in response to the shift of the stylus.Further provided is a means for raising and lowering the guiderail which adjusts the elevation of the partial sleeve and tone arm and accordingly adjusts the vertical tracking angle of the stylus in the record groove.
