Title: Porcelain composition for magnetic head
Inventor: NAKAMURA TSUNEHIKO
IPC: G11B5/60
Filed: 1990-03-08
Abstract: PURPOSE:To obtain the subject porcelain having a thermal expansion coefficient similar to that of Mn-Zn ferrite, excellent in processability and free from a pore by blending a prescribed ratio of Ca and Ti as the porcelain-constituting oxide and specifying the average crystal grain size. CONSTITUTION:A porcelain composition containing Ca in an amount of 40-48mol% on CaO base and Ti in an amount of 52-60mol% on TiO2 base and having 4-7mum average crystal grain size. The reason why the above-mentioned composition is limited is that the thermal expansion coefficient is <105X10<-7>/ deg.C unsuitable for a slider material for Mn-Zn ferrite in case of <40mol% Ca on CaO base and >60mol% Ti on TiO2 base. Contrary to this, in case of >48mol% Ca on CaO base and <52mol% Ti on TiO2 base, TiO2 crystalline phase in the porcelain is reduced and growth of calcium titanate crystal grains can not be prevented. Abnormal grains are produced therefor and pores are left in the porcelain in that case.

Filed: 1983-04-04
Abstract: PURPOSE:To decrease the fluctuation in the sensitivity of focus error by extracting and outputting a focus error signal when an optical spot is not irradiated on a pit so as to eliminate the effect of the shape of pit. CONSTITUTION:An extracting means comprising a sampling pulse generating circuit 7 inputting a recording information signal (RF signal) to a focus error detector and a sample-and-hold circuit 8 inputting an output of a subtraction circuit 4 and sampling and holding the output of the subtraction circuit 4 with a pulse outputted from the sampling pulse generating circuit 7 is provided so as to apply an output of the sample-and-hold circuit 8 to a focus servo device as a focus error signal. The time of generation of an output of a delay circuit 7-4 is within a period when the optical spot is not irradiated to the pit, that is, within the period when the RF signal is at high level. Thus, an output of the subtractor 4 is sampled and held during the period when the RF signal is at high level and the fluctuation in the sensitivity of focus error detection due to the shape of pit is eliminated.
