Recording present invention, wireless Smart hard-disk drive (wsHDD) device (RD) comprises at least a recording function, which is disclosed. converts external analog multimedia Signals into multimedia data and records them onto a Storage medium. Examples SUMMARY OF THE INVENTION include digital Still camera, digital camcorder, and digital 0022. To address the storage needs of portable multime voice recorder. Playing device (PD) comprises at least a dia devices, the present invention discloses a portable wire playing function, which converts multimedia data into per less Smart hard-disk drive (wsHDD). It comprises a wireless ceptible (analog) multimedia signals. Examples include direct communication means with associated multimedia audio player (e.g. MP3-player, CD player), movie player devices. Here, the word "wireless” means no user interven (e.g. VCD/DVD player, microdisplay-based video-player), tion is needed during data transfer, i.e. a user does not need portable game machine (e.g. Game Boy), and global posi to connect a wire between the WSHDD and device; the word tioning system (GPS). Multi-function devices (MD) com “direct” means no computer is needed as intermediary prise both recording and playing functions. Examples during data transfer. With a huge Storage capacity, a Single include personal versatile recorder (PVR), camera (or video) portable wsHDD can store multimedia files for a large cellular phones with built-in MP3 player, and personal number of multimedia devices. Namely, wsHDD will digital assistant (PDA). become a universal multimedia Storage platform. It can 0.015 Recently, the storage capacity of small form-factor replace various Storage media, Such as removable flash cards (portable) hard-disk drive (HDD) increases tremendously: (e.g. CF, MM, SD, MS, XD), videotapes (e.g. VHS, 8 mm, for 2.5" HDD, it has reached 80GB; for 1.8" HDD, 40GB Hi8, MiniDV, MicroMV), and optical discs (e.g. CD, VCD, (this number will soon reach 100 GB).
