Abstract

PURPOSE:To obtain a magnetic head which is inexpensive and has a high efficiency, and to elevate its mechaical reliability, by providing a center track corresponding to signal track width, and a slide surface for generating the floating force, on a magnetic core and the opposed surface of a recording medium of a slider, respectively. CONSTITUTION:A core and slider assembly body 30 is formed by joining in one body slider chips 31a, 31b consisting of a ceramic material, through glass 34a, 34b, onto both sides of a core chip 32 consisting of Mn Zn ferrite which has been formed in one body by sticking a winding yoke 32a on which a winding window 39 has been formed, and an I core 32b by use of glass so as to form a recording and reproducing gap 33. Subsequently, slider slide surfaces 38a, 38b for generating the floating force are formed on the chips 31a, 31b of the op- posed surface side to a recording medium of the assembly body 30, and grooves 37a, 37b for balancing the floating force and returning force are formed between the chip 32 and the chips 31a, 31b. Also, a center track 38c corresponding to the signal track width is formed on the opposed surface side to the recording medium of the chip 32.
