Filed:

Aug 28, 1996

Appl. No.:

08/712638

Inventors:

Mark L. Elliott - Eden Prairie MN
Paul A. Galloway - Prior Lake MN

Assignee:

Seagate Technology LLC - Scotts Valley CA

International Classification:

G11B 5596

US Classification:

360 7708, 360 75

Abstract:

A servo system positions a transducer over a disc surface in a disc drive system. Disc surfaces in the drive each have a plurality of spaced servo samples recorded thereon. The servo samples on at least two of the disc surfaces are recorded in skewed relation to one another. A plurality of transducers are provided and one transducer is associated with each one of the plurality of disc surfaces. An actuator arm assembly is coupled to the transducers to move the transducers relative to the disc surfaces. A servo control system is coupled to the actuator arm assembly to control position of the actuator arm assembly. The servo control system includes a reader configured to read servo samples from at least two disc surfaces such that at least two servo samples are read within one servo time period.

International Classification:

G01V 3/00

US Classification:

324309, 324307, 324318

Abstract:

A spin locked balanced steady-state free precession (slSSFP) pulse sequence combines a balanced gradient echo acquisition with an off-resonance spin lock pulse for fast MRI. The transient and steady-state magnetization trajectory is solved numerically using the Bloch equations and is shown to be similar to balanced steady-state free precession (bSSFP) for a range of T2/T1 and flip angles, although the slSSFP steady-state could be maintained with considerably lower RF power. In both simulations and brain scans performed at 7T, slSSFP is shown to exhibit similar contrast and SNR efficiency to bSSFP, but with significantly lower power.

Appl. No.:

6/248644

Inventors:

Mark L. Elliott - Richfield MN

Assignee:

Magnetic Peripherals Inc. - Minneapolis MN

International Classification:

H02P 506

US Classification:

318312

Abstract:

A digital control system is provided to regulate the speed of a brushless DC motor via pulse-width modulation. Digital counters are used to measure the difference between the time for a motor revolution and a reference time. This time difference is in turn used to control the time until the application of power during a fixed period. A motor speed decrease increases the difference in time between a motor revolution and the reference time. This decreases the power pulse delay time and results in an increased power-on time to bring the motor back up to nominal speed.
