Appeal No. 1995-3501 Page 5 Application No. 07/927,788 If a file directory group runs out of space to store any more file directory entries for its path, a new file directory group is allocated. The last block of the old file directory group points to the first block of the new file directory group, and vice versa. This doubly linked chain permits searching the file directory groups having a common path either backwards or forwards. This technique also allows for an unlimited number of data files per path on the WORM volume, subject only to the physical space limitations of the WORM volume. [Specification at page 6.] The specification discloses that the PVR table contains the address of the next file directory group and the address of the previous file directory group, if any, for the path to allow chaining of all file directory groups per path (Specification at pages 19 and 20). The examiner is of the opinion that the Path Table of Miki disclosed in Figures 7D and 8C is a PVR table as recited in claims 87 and 90. In this regard the examiner is of the opinion that what Miki calls directory files i.e. AAA, BBB, CCCCC, and A to K are file directory groups. However, directories AAA, BBB, CCCCC, and A to K do not comprise a path name and a plurality of file directory blocks each of which contain a plurality of file directory entries (See Figures 7BPage: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
