As a magnetic resistance of the joint parts increases, the reproduction efficiency of a magnetic head is lowered and hence, a low melting point glass is formed by about 0.2mum by sputtering method at the joint parts for thermal pressure welding. The height of a magnetic head tip part is about 0.2mm, the thickness of the thin film coil 0.2mm and the total height is below about 0.4mm, preferably below 0.55mm.

IPC: G11B20/18
Filed: 1991-12-09
Abstract: PURPOSE:To promote the reliability of an RAW check by checking reproducing data based on a space between the number of errors in detecting the reproducing data and a resynchronizing byte. CONSTITUTION:When a synchronizing byte in a regenerative signal is detected by a synchronizing byte detecting circuit 7 and is sent to a demodulation circuit 6, an inputted regenerative signal is demodulated by the circuit 6. At this time, a detected resynchronizing byte signal is outputted to the demodulation circuit 6 by a resynchronizing byte detecting circuit 11, and also a resynchronizing trigger pulse is outputted to a resynchronizing interval register 12. Then, the demodulation is resynchronized in the demodulation circuit 6, and the number of errors is detected in an ECC circuit 3, while based on two values set by the register 12 corresponding to an interval of the resynchronizing trigger pulse, the detection of the resynchronizing byte is decided in a CPU 13. When it is decided that the data is not normally written, sector alternation processing is performed in rewrite processing area. By this method, an RAW check function is enhanced, and hence the reliability can be promoted.
