<p>A double-sided recording device supports two transducers (24, 24') in fixed relation on opposite sides of a storage medium (6) so that a fixed separation (d') is maintained between the transducers. By making the separation (d') substantially greater than the transducing cross-section of the medium, only one transducer at a time can effectively interface with the medium. Each transducer (24, 24') is mounted in a stabilizing device (18, 18') having an air bearing surface (26, 26') that promotes an effective interface through one-sided contact with the medium. In one embodiment, the medium is supported on a drive spindle (13B) that moves axially between two playing positions, one (Fig. 7) in which the medium is brought into operative relation with the first transducer (24) and the other (Fig. 8) in which the medium is brought into operative relation with the second transducer (24'). In another embodiment, the transducers are supported in fixed relation on a yoke (96) that moves (Figs. 10A, 10B) in relation to a fixed motor spindle (13B).</p> |
