TFS: A Novel File System for Mobile Multimedia System
This paper presents a novel high performance file system for mobile multimedia system: Track File System (TFS) based on the researches of the character of modern disk drive. This paper firstly analyses the non-linear seek latency character of modern disk drive, and then indicate the drawback of UNIX fast file system (FFS) due to small writes of mobile multimedia files. Then, this paper describes a novel disk layout of TFS: putting the meta-data and data into the same track. This disk layout of TFS can effectively depress the seek overhead of access for mobile multimedia files and greatly improve file system throughput. The experiments of this paper show that TFS is a high performance file system for mobile multimedia system.
