“…For the three films studied here the predicted variations of transition widths with packing density according to (8) are shown in figure 7. For comparison purposes the transition widths calculated according to the selfdemagnetization limit, even taking into account the effects of interbit interactions, are considerably smaller than for the write loss limited case and so the recording process in these films was write loss limited as confirmed elsewhere [10]. The fact that predicted transition widths are smaller than observations could be due to the use of non-optimum write currents during recording, imperfect knowledge of hysteresis properties of the media and conditions during the write process.…”

Nonlinearities in square wave recording on three rigid disks have been studied experimentally. Measurements of the roll-off curves and of the noise power spectra as functions of packing density both show that in square wave recording nonlinearities arise from transition width broadening at high densities. Transition width parameters measured by the two methods show excellent agreement over the whole range of packing densities studied.

“…Therefore, if the transition is not deformed by the influence of the secondary field, the transition lengths on various coercivities is determined by the field gradient of the primary field at the writing edge at which the field strength is equal to the coercivity. [2][3] In conclusion, the transition-length is determined by the relationship of (field gradient )-112, when the field is just over the coercivity. If the field strength equals the media coercivity, the transition is determined by the field gradient of zero.…”

This paper describes the influence of the head field on transition fonnation. Two types of MIO heads and three thin film media which have various coercivities were used for the investigation. MIO heads generate the secondary field as a result of ferrite saturation by flux concentrated in metal films in the gap region. A degraded field gradient, such as the secondary field, produces not only a wider transition region, but also a more irregular transition configuration. The transition length is detennined by the relationship of (field gradient)-1/2, when the field is just over the coercivity. If the maximum field strength equals media coercivity, then the transition is detennined by the field gradient of zero. The transition configuration fluctuates by means of increasing the transition noise, when the transition is spread by the degraded field gradient .
