MEMORY DRIVE FOR OPERATION ON NETWORK, METHOD OF ACCESSING FILE DATA IN SEQUENTIAL ACCESS STORAGE MEDIUM FROM NETWORK, MEMORY LOGIC INCLUDING LOGIC FOR CONVERTING COMMAND BASED ON FILE AND LOGIC FOR STORING TOC, MAGNETIC TAPE, AND LOGIC FOR ACCESSING DATA OF TAPE AND TOC REGION

摘要

PROBLEM TO BE SOLVED: To provide a memory drive logic and a stand-alone tape file structure.;SOLUTION: File transfer logic transfers file data to and from a network according to a first protocol. A medium access logic accesses a sequential access storage medium related to a drive according to a second protocol. A medium management logic converts a command based on a file received from the network according to the first protocol into a sequential access device command following the second protocol. A device command controls the access of data by the drive. The storage medium may be a magnetic tape including a data region for storing data in a file format and a table-of-contents (TOC) region for storing a table of contents which indexes the positions of files in the data region.;COPYRIGHT: (C)2007,JPO&INPIT
