Abstract :
A new inductive ring head configuration has been designed which utilizes a composite substrate of magnetic and nonmagnetic members for thin film processing and thereby has several features that are advantageous to a high density recording head, that is, 1) thin film poles, 2) etched track widths, 3) no secondary ferrite gap, 4) low reluctance bulk ferrite superstructure, and 5) ordinary wire wound coils.
