摘要： An optical data storage system utilize a fully or partially transmissive data storage medium or disk. The optical system includes a platform capable of moving either radially or pivotally relative to the disk. A head has a first and a second optical arms secured to the platform. One optical arm is positioned below the storage medium, and the other optical arm is positioned above the storage medium. One of the two optical arms includes a light source connected to the platform for generating a collimated light beam, and a first reflective mirror distally connected to the platform for reflecting the collimated light beam toward the storage medium. The other optical arm includes a photo-detector connected to the platform, and a second reflective mirror distally connected to the platform for reflecting the light beam impinging upon it to the photo-detector. In one embodiment the light source is disposed below the disk while in another embodiment the light source is disposed above the disk. The optical system may also be used as a magneto-optic system capable of recording data onto the disk by the addition of a magnet secured to at least one of the reflective mirrors. The magnet is cylindrically shaped and hollow along its axial length, and allows the laser beam reflected by the mirror to pass though and along its axial length. In yet another embodiment the laser source includes a reading laser source with a weaker light intensity for reading the recorded data onto the storage medium, and a recording laser source with a higher light intensity for recording data onto the storage medium.
