To provide a production control system by a magnetic recording means which can efficiently manage articles to be produced in each lot, in a process in which a plurality of articles to be produced, are subjected to a series of working steps in each lot.

Sub-recording means 13 store therein individual data for each products, in a main recording means 12, and then store new data while carry out production control for a series of working steps in accordance with the data previously stored. After the series of working steps are completed, the main recording means 12 stores therein new data for articles to be produced. The main recording means 12 moves the sub-recording means 13, successively, to positions corresponding to respective steps in the series of working steps in accordance with a steam of the articles to be produced. The movement of the sub-recording means 13 is synchronized with the movement of the articles to be produced, and accordingly, the streams of data and articles to be produced are coincident with each other.
