Hard Disk Slider Analysis Application

• Developed a program reading large(~3GB) csv files that come from a sophisticated machine which

analyzes hard disk sliders by reading its reading and writing resistances, and Noise - nV/sqrt(Hz).

• Used OOP to develop a relationship between wafers, sliders, cycles(noise) and cycle peaks.

• Implemented a functionality which will find peak details in each cycle, alleviating unwanted random

noise/spikes, graphing all its information using Matplotlib.

• Created a function calculating deviation in resistances and flags ‘bad measurement’ if it’s too high.

• Used Config Parser to save variables for different types of analysis and turned the program into an

executable file for Western Digital at Philippines to constantly measure data daily.
