L O L. Poor Salim, he almost choked on the bait. Damn, he wetted his panties again. Gotta remember not to use too big a bait to catch a small fish the next time. Let's move on, shall we?
As users of information, here's another description of Magneto-optical recording from the Quantum web site. Note how Quantum describes the process of writing, using a combined magnetic and optical process, and reading, using an optical process. Note also that Quantum owns a piece of Terastor. Somebody also told me that the January 97 issue of Data Storage contains an update about how Hitachi/Maxell/Sanyo just achieved 14 GB per side using a presumably similar MO device. So Terastor's 20 GB per side may not all be that big of a leap. Speed-parity and cost-parity are the key things to watch here.

'...The disadvantage of MO technology is that, because of the high intensity of the magnetic field created with the combined use of the read/write head and laser, the drive cannot change the field polarity very quickly. Therefore, the drive must pass over the disk twice to write to it. In the first rotation, all the bits are set to the same orientation, effectively erasing the data; in the second rotation, some of the bits are reoriented to the opposite pole to distinguish the 0 data bits from the 1s. Even though some MO drives spin, on the average, at rpms comparable to hard disk drives, the two rotations
required for writing data make them twice as slow as hard disk drives
during write operations. Of course, MO drive manufacturers are at work
trying to compress the writing process into a single disk rotation. So, MO drives with one-pass writing capabilities should be available soon...."
