1) Large 9.1 GB Capacity Made Possible by New Technology
Using its "Magnetically-Induced Super Resolution (MSR)" and"Land and Groove Recording" advanced core technologies, Sony has achieved a high-density data recording system for large-capacity needs. New MO disks have 14 times the capacity of first-generation 650 MBytes MO disks. |

2) Fast 6.14 MBytes/sec. Data Transfer Rate
A high-performance RISC CPU and 8 Mbytes of cache memory, enhanced with Sony's proprietary "S-Cache" data algorithm, allow the SMO-F561/S561 to transfer data up to 6.14 MBytes/sec. - sufficient for handling MPEG-2 video. |
|
3) Excellent Reliability and Durability that only MO Drives offer
Compared to other removable media, MO storage media is very resistant to damaging elements such as grime, dust, temperature, and magnetic fields. Sony MO drives feature an MTBF of 300,000 POH, MSBF of more than 750,000 cycle. |
