OPTICAL DATA STORAGE AND RETRIEVAL SYSTEM AND METHOD. |
摘要 |
<p>A first write encoder encodes digital data in a first, high-density format. A second write encoder encodes digital data in a second, low density (i.e., ANSI) format. A first read decoder decodes digital data from the first format. A second read decoder decodes digital data from the second format. A disk drive receives a replaceable 90 millimeter optical disk. A read/write head reads encoded data from and writes encoded data to a 90 millimeter optical disk received by the drive. In a first mode, the first write encoder is connected between a source of digital data and the read/write head, and the first read decoder is connected between the read/write head and the utilizing apparatus. In a second mode, the second encoder is connected between the source and the read/write head, and the second read decoder is connected between the read/write head and the utilizing apparatus. <IMAGE></p> |
