Harddisk Drive atau yang sering dsebut sebagai ‘ harddisk saja ‘ merupakan salah satu komponen terpenting dalam komputer. Harddisk Drive mempunyai nama lain yang secara umum disebut recording media yang berfungsi untuk menyimpan data ( informasi ). Banyak dari kita yang menggunakan harddisk, tetapi mungkin sedikit sekali orang yang mengetahui asal usul dari Harddisk Drive. Oleh karena itu dalam forum ini saya mencoba untuk membahas asal usul dari Harddisk terlebih dahulu.
