Abstract
A recording medium includes a transparent substrate and a recording layer formed thereon for recording information, and a component made of material with a large loss factor, such as butyl rubber, bond magnet, etc. By suppressing recording medium vibration resonance from a recording and reproducing device, an improved frequency characteristic of a linear motor can be achieved, thereby enabling high access speed. Preferably, the large-loss material also provides a directional magnetic field which facilitates magneto-optical rewriting on the recording layer.
