Anyone know any detail concerning SEG looking to find a head supplier for their drives? What are the pros/cons of this action?

Thanks for your always cogent explanations. If you'd please, I'd like your thoughts on what is tougher to do, increasing the tpi or increasing the bpi?

JoeBiker:

This would only be true if Seagate is "short-stroking" the drive, thus using less of the usable area of each surface (the outside, where performance is higher), and making up for the capacity loss with greater areal density. This is not a common technique..."

Is this what you mean by "short-stroking?" Thanks in advance.

Seagate engineered its second-generation improvements by an unusual shift: switching to 3-inch platters. Smaller platters held the key to both the performance gains and the power reduction.

"We loaded the head-disk assembly with 3-inch platters instead of 3.5-inch disks," Thibodeau said. "That reduces the mass and windage, which lets us cut power consumption. It also effectively shortens the stroke, since we don't have to go over the whole surface of a 3.5-inch disk."

Joe,

When I say "number of platters", I was referring to GB/platter, meaning that a DD maker is going to try to hit "X" capacity with "Y" platters. I think in a technical sense you definitely described it better in your last paragraph. I've got just enough technical knowledge to be dangerous.

Although, you can also say that if Brand B can't hit the highest TPI, then the solution os to get extra umph from the BPI (sort of a half empty/half full way of looking at it).

Regards,

Hey Biker Dude! How 'bout looking into the new IBM drive. At 2.7GB/in^2 will they run into DTR problems?(their 8.4GB DD was as slow as dirt = 127Mb/s internal) Have they slowed down the rot speed, or seriously sped up the electronics? I am assuming GMR probably allows them to increase bpi, not necessarily tpi?
