Title: Magnetic card recording/reproducing method and magnetic card used for it
Inventor: SAITO KAZUHIRO
IPC: G11B5/706
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To record and reproduce a magnetic card capable of obtaining a high reproducing output even when coercive force of a magnetic powder used for the magnetic card becomes high by recording with a recording current that a rise time of a recording current waveform is within a half period of the recording current when information is recorded on a magnetic recording layer by a magnetic head. SOLUTION: When the information is recorded on the magnetic recording layer of the magnetic card by using the magnetic head, the reproducing output is improved by gradually inverting the recording current. In the usual recording current waveform (a), the recording current is inverted drastically. The recording current waveform or a pulse waveform of a recording current pulse at the time of gradual inversion may be made forms as shown in (b)-(d) at the time of rise, and as shown in (d)-(h) at the time of fall. At this time, when recording information is recorded using the magnetic head, the matter that 2ts /T is 40% or above is preferred.

Title: Processing method for insulating film

IPC: H01L21/302
Filed: 1982-02-22
Abstract: PURPOSE:To prevent the disconnection of conductive wiring by forming the opening section of the insulating film with a tapered shape with no stepped difference to a PSG film section. CONSTITUTION:An SiO2 film 5 with 6,000Angstrom  thickness and a PSG film 6 with 2,000Angstrom  thickness are formed onto a substrate in succession, and the PSG film 6 is selectively removed at first while using a resist pattern 7 as a mask. The SiO2 film 5 is removed by using an aqueous solution containing 6% fluoric acid and 30% ammonium fluoride. The etching rate of the SiO2 film 5 is experimentally measured previously and etching time is calculated beforehand at that time, and the siO2 film 5 is left only by approximately 500Angstrom . A resist is exfoliated, and the PSG film remaining on the surface except a window section and the SiO2 film 5 left thinly are removed by using an etching liquid of the PSG film 6 again. The PSG film 6 is also removed completely from the upper section of the SiO2 film 5 except the window section if etching is completed at a point of time when the SiO2 film 5 left thinly is precisely removed completely because the etching rate of the PSG film 6 is several times as fast as the SiO2 film 5. The tapered shape of a gentle section up to an upper edge from a lower edge of the opening window section is formed through above-mentioned processes.
