Patent JP-H0312076-A (JP)
Title: Magnetic disk device
Inventor: NISHIYAMA NOBUMASA
IPC: G11B21/02
Filed: 1989-06-09
Abstract: PURPOSE:To increase the recording density without increasing the cost by reducing the track width of a magnetic disk toward the outer circumference from the inner circumference. CONSTITUTION:When an angle theta is formed by a normal of a gap 102 and a track 105, the track width Tw=Gcostheta. When a magnetic head 101a is positioned in the innermost circumferential track 105A, theta=0, and when the head moved toward the outer circumference, the angle is increased and Tw is continuously diminished to increase the number of tracks so that the recording density can be increased. Even when an arm 110a (110b) is expanded and shrunk by a vibration and a temp. change in the radial direction of the magnetic disk 107, a data head 101a (servo head 101b) is positioned correctly by a moving mechanism 109a (109b) so that information can accurately be recorded. Then, a magnetization inversion line 204A is parallel to the track widthwise direction in the innermost circumferential track 105A, whereas an azimuth formed by inversion lines 204B and 204C is set as 2theta in an even track 105B and an odd track 105C. Since the bigger the azimuth the outer the circumference and hence the harder the cross talk, the number of tracks is increased by making a space between the tracks 105 close to each other so as to increase the recording density.

Inventor: HIURA YOHEI
IPC: H01L27/115
Filed: 1992-06-05
Abstract: PURPOSE:To make it possible to protect the boundary part between a source part and a channel part under gates by the sidewalls of cells in the case of removal of a field oxide film at the time of formation of the source part in the manufacture of a tunnel current erase type EPROM, to lessen an irregularity in the thickness of a gate oxide film and to inhibit an irregularity in the erase characteristics of the cells. CONSTITUTION:In a tunnel current erase type EPROM, floating gates 114 and control gates 115 are formed on a P-type silicon wafer 101 consisting a memory cell main part and a source region 112 and drain regios 113 are formed in the wafer 101. When such the EPROM is manufactured, an etching condition to generate a polymer is used at the time of a selective etching for removing a field oxide film in a SAS technique and the boundary parts between the source part and the gates are made to protect by making this polymer adhere on the sidewalls of two-layer gates. Thereby, a generation of a step in the surface of the silicon substrate is prevented at the boundary between the source part and a channel part under the gates and an irregularity in the erase characteristics of cells is inhibited.
