Abstract
A system for manufacturing a thin-film magnetic head having a means for cutting a wafer into bars, each bar having a plurality of thin-film magnetic head sliders which are sequentially coupled with each other, a means for identifying the bar to be worked to generate an identification signal which indicates identity of said bar, a means for obtaining data of said bar in a unit of bar depending upon said identification signal, and a means for processing at least one working of said bar on the basis of said obtained data of said bar.
Claims7
A system for manufacturing a thin-film magnetic head comprising:
- means for identifying a bar to be worked to generate an identification signal which indicates identity of said bar, said bar being fabricated by cutting a wafer into bars, each bar having a plurality of thin-film magnetic head sliders which are sequentially coupled with each other;
- means for obtaining data of said bar in a unit of bar depending upon said identification signal, said data obtaining means including means for extracting said data from a table which stores retrievable relationships of identification signals and data of bars in a unit of bar;
- and
- means for processing at least one working of said bar on the basis of said extracted data of said bar.
