To the Net; I just got the latest list of RLL 2/7 certified disk drives from Scientific Micro Systems (the guys that make OMTI controllers). I just thought you might find the following info useful if you happen to go shopping for an RLL controller to boost your storage capacity. Maker Model Capacity Access Size Height Phone in mS. ----- ----- -------- ------ ---- ------ ----- ATASI 3085 109.1 29 5.25" full 408-436-0335 Lapine LT300 32.8 65 3.5 half 408-262-7077 Microscience HH-330 32.6 80 3.5 half 415-961-2212 HH-738 32.6 80 5.25 half Miniscribe 3438 32.7 85 5.25 half 303-651-6000 8438 32.6 68 3.5 half Peripheral PT 238R 32.7 40 3.5 half 805-581-1000 Technolgy PT 357R 49.1 40 3.5 half Priam V170 91.9 30 5.25 full 408-946-4600 V185 108.6 30 5.25 full 514 179.2 20 5.25 full 519 244.4 20 5.25 full Seagate ST238 32.7 65 5.25 half 408-438-6550 ST251R 43.6 40 5.25 half ST277R 65.4 40 5.25 half ST4077R 68.1 28 5.25 full ST4144R 122.7 28 5.25 full Toshiba MK-53FB 55.2 25 5.25 full 408-727-3939 MK-54FB 77.3 25 5.25 full MK-56FB 110.5 25 5.25 full The capacities are the formatted capacity of the drives based on the "usual" RLL-2/7's 26 sector per track format. I heard that Segate is doing some research to push RLL another notch next year. The current 2/7 yeilds a 50% storage boost over MFM. Seagate is looking into 4/9 (I think those are the digits ?) to yeild a 100% incease over plain MFM. If your favorite drive is not on the above list, it could well be RLL capable. I'm not sure if this list is anywhere near exhaustive! --Bill Bill Mayhew, EE Lab Div. Basic Med.
