New Headloading Mechanism HLM-2011 and High Data Rate Cartridge PAC-2011

New Headloading Mechanism HLM-2011 and High Data Rate Cartridge PAC-2011

Guzik introduces a new front-end to its Spinstand Models V2002 and DTR 3000, which includes new Headloader Mechanism HLM-2011, new cartridges PAC-2011, and new Universal Preampilifer UP11.

Guzik MR7 Read/Write Headamplifier – Discontinued

Guzik MR7 Read/Write Headamplifier – Discontinued

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

Guzik MR-5 Read/Write Amplifier for GMR – Discontinued

Guzik MR-5 Read/Write Amplifier for GMR – Discontinued

The Guzik MR Amplifier Revision 5 is a next generation of the Guzik head amplifiers.

Guzik MR5-L Read/Write Headamplifier – Discontinued

Guzik MR5-L Read/Write Headamplifier – Discontinued

The Guzik MR-5L read amplifier is designed to work with the high-impedance TMR heads. The impedance of such heads can be as high as 1000 Ohm, so it is impossible to achieve a high bandwidth with a high-impedance amplifier. This is the reason, why MR-5L is a current-sense low-impedance amplifier with voltage bias.

Head Amplifier Injector for V2002 – Discontinued

Head Amplifier Injector for V2002 – Discontinued

Bandwidth from DC to 6 GHz Required for frequency response measurements of high bandwidth analog

Active Head-Impedance Injector for Head Amplifier of V2002 Spinstand – Discontinued

Active Head-Impedance Injector for Head Amplifier of V2002 Spinstand – Discontinued

Guzik active high-impedance injector is designed for the measurements of frequency response and the calibration of the low-impedance current-sensitive head amplifiers. The injector also provides the ability to evaluate the performance of the head-amplifier heater driver. A current probe can be connected to the injector, in order to measure write current of the head amplifier.

Piezo-Actuator Cartridge with AE Sensor

Piezo-Actuator Cartridge with AE Sensor

The new generation of Guzik cartridges is equipped with Piezo actuator to achieve higher servo closed loop bandwidth. The typical bandwidth is in the range of 2–3 kHz. This allows for non-repeatable run-out reduction down to 0.35–0.60 nm (0.014–0.024 Inch) , 1. The higher servo bandwidth also improves seek time, which leads to test time improvement for several tests.

V2002 Spinstand Automation for Head Testing

V2002 Spinstand Automation for Head Testing

Automated Protective Cover and Disk Shroud: Improves the repeatability and the accuracy of HGA testing results. Protects media and operator while changing HGA cartridges without stopping spindle. Covers media to protect it while spinstand is not in use. Automated disk shroud movement eliminates the need to manually release, move, and lock the disk stabilizer shroud
