Abstract
A method for manufacturing a thin-film magnetic head includes a step of cutting a wafer into bars, each bar having a plurality of thin-film magnetic head sliders which are sequentially coupled with each other, a step of identifying the bar to be worked to generate an identification signal which indicates identity of the bar, a step of obtaining data of the bar in a unit of bar depending upon the identification signal, and a step of processing at least one working of the bar on the basis of the obtained data of the bar.
Claims7
A method for manufacturing a thin-film magnetic head comprising the steps of:
- cutting a wafer into bars, each bar having a plurality of thin-film magnetic head sliders which are sequentially coupled with each other;
- identifying the bar to be worked by generating an identification signal which indicates identity of said bar;
- obtaining data of said bar depending upon said identification signal by extracting said data from a table which stores retrievable relationships of identification signals and data of bars individually on a per bar basis, said data including information which are inherent to said bar and are used for working of said bar;
- working said bar on the basis of said extracted data of said bar;
- and
- storing data which includes measured information of said bar after said working step is performed in said table in relation to said identification signal.
