ABSTRACT:
A double-sided recording device supports two transducers in fixed relation on opposite sides of a storage medium so that a fixed separation is maintained between the transducers. By making the separation substantially greater than the transducing cross-section of the medium, only one transducer at a time can effectively interface with the medium. Each transducer is mounted in a stabilizing device having an air bearing surface that promotes an effective interface through one-sided contact with the medium. In one embodiment, the medium is supported on a drive spindle that moves axially between two playing positions, one in which the medium is brought into operative relation with the first transducer and the other in which the medium is brought into operative relation with the second transducer. In another embodiment, the transducers are supported in fixed relation on a yoke that moves in relation to a fixed motor spindle.
