Seagate Technology Inc, Scotts Valley, California yesterday plunged into the 3.5 Winchester market with six new drives, all featuring sputtered thin-film media from Seagate Magnetics and open-loop rotary-stepper actators for an average access time of less than 30mS. The new 3.5-inch drives require only 9W power for the Run-Length Limited and MFM models and 11W for the SCSIs. The new product family is available with embedded controllers and SCSI interface, or with the standard ST412 interface using MFM or RLL recording. The SCSI drives are the 30Mb ST138N and 45Mb ST157N; and using RLL recording, the ST138R and ST157R offer the same formatted capacities. The ST125 20Mb and ST138 30Mb drives use the ST412/MFM interface. Evaluation units are set for the second quarter 1987, with volume production to begin in the second half of 1987. The products will be produced at Seagate’s Far East facilities. The six new 3.5 drives range in price from $495 to $695 in quantities of 500 up.
