OPTICAL RECORDING-REPRODUCING DEVICE OF RECORD CARRIERS AND OPTICAL MEMORY SYSTEM COMPRISING SUCH A DEVICE |
摘要 |
The device makes it possible to optically inscribe and/or read at least two facing sides of disks in an optical memory system, whose disks are stacked. A linear motor displaces a mobile means incorporating recording-reading heads. These heads receive via a bidirectional optical connection data to be inscribed and coming from fixed light emitters-receivers. Each of the recording heads comprises two focusing lenses associated with one of the two facing sides of the disk. According to a first variant, the two sides can be read simultaneously, each of the lenses being associated with its own control device. In a second variant, a single control device is provided and the two focusing lenses are integral with one another, each side being read or inscribed in succession. |
