Appeal No. 1998-1658 Application 08/343,876 (col. 6, lines 33-35), which are known to have a high saturation flux density (col. 1, lines 33-46). We find that the head structure of Okuda meets the limitations of the head in claims 1 and 8. However, Okuda does not disclose the direction of movement of the head relative to the tape and does not disclose the magnetic recording material. Appellants argue that Okuda has a structure that is different from that of recording heads recited in the instant invention (Br12). We disagree. Appellants do not explain how the head structure in Okuda is different from that which is claimed. The structure of the head in Okuda meets the claim requirements for a head having a gap edge of high saturation magnetic flux density material which is at least 1.2 times that of a low saturation magnetic flux density material of the other gap edge. We find that Shimizu '178 discloses a recording media, as claimed, and that Okuda discloses a head, as claimed. As to whether it would have been obvious to combine the recording media of Shimizu '178 with the head of Okuda, Appellants argue that the combined disclosures fail to provide for a magnetic recording and reproducing system like that claimed, and also fail to provide any motivation to prepare the same (Br12). The Examiner responds that all the references are within the same field of endeavor, dynamic magnetic recording/reproducing, and therefore a - 18 -Page: Previous 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 NextLast modified: November 3, 2007
