MR7 READ/WRITE AMPLIFIER
Guzik MR7 amplifier is designed for high-speed operation with RWA-2000 series. Compared with MR5 head amplifier, it has much wider bandwidth of write and read channels and significantly faster rise/fall time of write current. As a result, the MR7 can operate with data speed up to 4 Gbit/sec.[more]

3D Pulse Profile Test for Nano-Scale Magnetic
Field Imaging with D5000 Signal Analyzer
The test captures data from
magnetic media and draws 3D and 2D plots of read-back
signal amplitude versus off-track offset and along-the-track direction. The acquisition is performed
using Guzik D5000 analyzer...[more]

Digital
Frequency Domain Analysis for D5000 Signal Analyzer
The D5000 Signal Analyzer opens
new possibilities for frequency domain analysis. This analysis is
performed by FFT of the read-back signal. As a result, spectrum analysis
is done in full bandwidth of analyzed signal and performed much faster
compare with analog point-to-point measurements...[more]

D5000
Digital Media Scanning
D5000 Signal Analyzer opens new possibilities
for media scanning. The analyzer can measure the amplitude defects
(such as missing pulses, super pulses, and thermal asperities), and
the time defects (such as transition shift). Up to 24 defect detectors
can run simultaneously, with different settings. The high-resolution
thresholds of the defect detectors and multi-threshold amplitude analysis
allow the digital media scanner to generate three-dimensional map
of the defects...[more]

Servo
Improvement Package
The servo improvement package increases
servo positioning accuracy up to 0.4 nm (0.016 µInch), 1 sigma,
increases accuracy and repeatability of Triple Track, Track Profile,
and W/R Offset measurements up to 0.5-0.8 nm (0.02-0.03 µInch),
1 sigma, and reduces production test time by saving 3-5 seconds per
head per test location, compared to a standard servo... [more]

Bit
Error Rate (BER) Module for WITE32
The BER Module is designed to provide
various tests based on Bit Error Rate (BER) measurement using PRML
channel. This module includes the following components: BER 747A Test,
BER Linear Density Test, BER Error Distribution Test, and BER Performance
Test...[more]

V2002
Spinstand Automation for Media Testing
The spinstand V2002 with the media-testing
automation loads and unloads the cap of the vacuum chuck and moves
the disk stabilizer shroud on and off media without operator's intervention.
As a result, less time is required for a media replacement, so the
same number of disks can be tested faster...[more]

V2002
Spinstand Automation for Head Testing
The automated protective cover and
the disk-shroud automation add more to the V2002 head-testing capability:
with the protective cover closed, the operator can safely change the
cartridges without stopping the spindle. Keeping media rotating during
the head changes eliminates the RRO drifts associated with starting
and stopping the spindle and increases the repeatability of the test
results. The cover automatically opens before loading the head onto
the media, closes after the head unloading, and moves outside the
spindle area, together with the shroud, for media replacement after
the test completion...[more]

D5000
Digital Signal Analyzer
The known disadvantage of a digital
system, compared to an analog one, is low processing speed. To overcome
this problem, the new Guzik D5000 Signal Analyzer uses a high-speed
digital data processor, which runs parametric measurements with speeds
up to 2.5 Gs/sec. The D5000 executes such complicated algorithms as
PRML decoding 100 times faster than is now available for digital oscilloscopes.
As a result, the D5000 has a near-real-time throughput...[more]
