• Separate Control Box and Spinstand for electrical and mechanical noise reduction.
• Low profile frame with air shock absorbers improves floor vibration isolation.
• Second revision of embedded servo with higher bandwidth.
• Suppresses floor vibrations more than five times better comparing to the previous model S-1701A+.
• Micro-positioning system with positioning repeatability less than 0.3µInch.
• Software controlled skew angle conversion without track repositioning.
• Easy conversion between head (HGA) and headstack (HSA) testing

Guzik S-1701B Micro Positioning Spinstand achieves better electrical and mechanical noise isolation compared to its predecessors S-1701A and S-1701A+ due to its separated control box and spinstand and air shock absorbers, installed inside the spinstand frame. It is equipped with a patented (US Patent: 5,382,887) closed loop positioning system consisting of a piezo substage and precision optical scales with 0.02µInch resolution. This, combined with second revision of the patented (US Patent: 6,023,145) embedded servo system, results in track positioning repeatability less than 0.3µInch, and more than five times suppression of low frequency floor vibrations in the range 0-25Hz. This capability is a requirement in MR-Head testing and high TPI track profile and track interference analysis.

S-1701B provides software controlled skew angle adjustment through a patented (US Patents: 6,006,614 and 5,254,946) software controlled mechanical configuration. Since the head gap is located in the center of a rotational system, skew angle control is accomplished by rotating the head around the head gap. In this manner the skew angle can be changed up to ±45° while remaining on the same track.

The capability of changing skew angles while remaining on track allows the user to perform a variety of measurements, including track profile analysis on a previously written track at varying skew angles. This measurement can produce a comb-shaped single-track profile plot.

Through a very simple mechanical conversion, S-1701B can be used for either head (HGA) or headstack (HSA) testing.

• Simultaneous and synchronous rotary and linear stage movements provide correct skew angles at all positions on the disk.
• Universal Micro Positioning Spinstand equipped for HGA, HSA, and Disk testing.
• Positioning repeatability less than 0.3µInch with optical scale resolution of 0.02µInch.
• Software controlled skew angles of ±45°.
• Optional clockwise (mirror) head loader allows testing bottom heads on the top.
• Interchangeable Head Stack (HSA) fixture can be designed to custom specifications.
• Interchangeable "Z-height" adapters, HGA mounting fixtures, and spindle chucks (disk sizes from 1.0" to 3.5").
• Optional optical alignment system available for head gap alignment within 0.001Inch to the center of the rotary system.
• Table top unit.
