Patent number: 6212032Abstract: A pseudo contact NPAB head slider configured for supporting a transducer proximate to a rotating disc. The slider includes two side rails extending almost to the trailing edge and a central air bearing island at the trailing edge, which form air bearing surfaces that develop positive lifting forces as the disc rotates beneath the slider. Two negative pressure air cavities are created, one proximate to each of the side rails in a central portion of the slider body, separated from each other by curved cross rails. In addition, two more negative pressure air cavities are created forward of the central negative pressure air cavities. The central and forward negative pressure air cavities on each side of the slider are divided by narrow central air bearing rails segments, which safely maintain the stable trapped drawing or suction forces in the cavities regardless of large skew angle variations while the disc drive is operating.Type: GrantFiled: February 18, 1998Date of Patent: April 3, 2001Assignee: Samsung Electronics Co., Ltd.Inventors: Ki-Ook Park, Dong-Seob Jang, In-Seop Jeong, Tae-Seok Park

Patent number: 6055129Abstract: A flying NPAB head slider configured for supporting a transducer proximate to a rotating disc. The slider includes two side rails extending from the leading edge to the trailing edge of the slider body, which form air bearing surfaces that develop positive lifting forces as the disc rotates beneath the slider. Two negative pressure air cavities are created, one proximate to each of the side rails in a central portion of the slider body, separated from each other by curved cross rails.

Patent number: 5917679Abstract: A negative pressure air bearing slider includes a slider body for flying above a surface of a recording disc during relative rotation of the recording disc. First and second projections extend from a lead portion of a principal surface of the slider body to define first and second air bearing surfaces, respectively, the first and second air bearing surfaces being spaced apart from each other in the lateral direction of said slider body. A third U-shaped projection extends from the principal surface and includes a curved front wall portion at least partially located between the first and second projections and first and second side wall portions extending from opposite ends of the curved front wall portion to a rear portion of the principal surface so as to define a rounded negative pressure cavity therein.Type: GrantFiled: August 22, 1997Date of Patent: June 29, 1999Assignee: Samsung Electronics Co., Ltd.Inventors: Ki-Ook Park, In-Eung Kim, In-Seop Jeong, Tae-Seok Park

Patent number: 5793407Abstract: A high density recording method for performing high density recording by reducing a light spot size in an optical pickup for recording information by scanning an optical disk with the light spot, spatially controlling the phase or the intensity of light being focused within the optical focal length of an objective lens by employing a diffraction optical element so as to form on the optical disk a light spot whose diameter is reduced according to the width of the portion for controlling the phase or intensity of the light. The distribution of the optical intensity is variable depending on the distance between the diffraction optical element and the optical disk, to thereby enable theoretically forming a limitlessly small light spot, and actually, greatly increase the recording capacity. The diffraction optical element can be used as a floating slider in an optical pickup having a swing arm.Type: GrantFiled: July 27, 1995Date of Patent: August 11, 1998Assignee: Samsung Electronics Co., Ltd.Inventors: Tae-seok Park, Chul-woo Lee, Jang-hoon Yoo

Patent number: 5526331Abstract: A dual disc recording/reproducing apparatus and recording method. The apparatus includes a reproducing deck unit and a recording/reproducing deck unit with both being controlled by one control unit. The method comprises the steps of recording on a disc a first program and a disc playing time on the lead-in area thereof unless data is recorded on the disc, recording the data onto the next recording area of the lead-out area if data is already recorded on the disc, and then recording the lead-out to process a present lead-out area as a bad block area. The next step is recording a new lead-out at the end of the disc playing time, and then processing the previous and next blocks, including the present lead-out area, as a bad block during the recording of the data, processing the previous and next blocks, including the lead-in area, as a bad block, and then recording the data in the program memory area onto a new lead-in area.Type: GrantFiled: February 22, 1995Date of Patent: June 11, 1996Assignee: Samsung Electronics Co., Ltd.Inventors: Tae-seok Park, Seung-tae Jung, Jung-hoe Kim
