Ahhh Don, I remain hopefull that you are correct but also remain convinced that we are in for a little more down news before the up begins. I am assuming that we are talking APM (and disk drives for that matter). I belive that inventory work off and difficulties with MR are deeper then we are currently led to believe. Also, you said <The pico form factor is estimated to double yeilds>. While it is true that the pico slider allows 14,700 sliders per six inch wafer to be fabricated vs. 8,400 of the "nanoslider" this doesant necessarily mean a 50% improvement in yields. In fact, the pico production throughout the industry will probably experience a yield hit as the industry learns how to handle them. They are substantially smaller (50% the size of a nanoslider) and the resulting difficulty in handling at HGA fab and HSA (head stack) fab is non-trivial. In addition non variation in sputtering (wafer fab) becomes more critical as does the process steps of polish, slicing, row bonding, edge blend, etc. All these steps become a little more dicey with the diminutive pico slider. By the way, Peripheral Research Corp. in Santa Barbara has published a report that states that Pico sliders were approx. 37% of head production (all suppliers) in 1997 and estimates that they will represent 67% of total production in 1998. It is just one more transition faced by APM and the industry at large. Want a quick inventory on what they are all wrestling with? Transition to MR?GMR, transition to Pico Slider form factor, integration of semi wireless suspensions, transition to lower flying heights, and transition to lower stiction-friction characteristics requiring new edge blend and air bearing designs. In addition, on the business side: transition of the industry to a BTO model, increased competition for fewer accounts, and the Asian economic dilemma, (is it good for them or bad for them?). Like the old joke goes...gotta be a pony in that pile somewhere. I am looking for the pony! Best, Stitch Best, Stitch
