MO media with 9.1 GByte
With the SMO-F561, Sony has introduced the next generation of its magneto-optical drives (MO), which can store up to 9.1 GB on a 5.25-inch medium. This means that Sony has almost doubled its capacity.
In addition, the transmission speed was increased by around 20 percent. Sony achieves the higher capacity with the new 'magnetically-induced super resolution' technology, which enables the drive to read magnetic recordings that are smaller than the laser spot. The drive can, however, continue to read and write older media, such as the 650 MByte MO disks of the first generation. The drive has an 8 Mbyte buffer and delivers the data to the PC or Mac via a Fast SCSI connection. The disks rotate 3000 times per minute and the average access time should be 25 ms. A maximum transfer rate of 20 Mbytes per second should be possible. The device costs 2,600--2,850 dollars and should be available in stores from early 2001
