要想了解軟盤(pán)和光盤(pán)中的信息，就必須把他們分別插入到軟盤(pán)驅(qū)動(dòng)器和光盤(pán)驅(qū)動(dòng)器中，供計(jì)算機(jī)對(duì)上面的數(shù)據(jù)信息進(jìn)行識(shí)別和處理。
軟盤(pán)驅(qū)動(dòng)器和光盤(pán)驅(qū)動(dòng)器都位于機(jī)箱中，只把它們的"嘴巴"露在外面，隨時(shí)準(zhǔn)備"吃進(jìn)"軟盤(pán)和光盤(pán)。
至于硬盤(pán)，由于它是不可移動(dòng)的，所以被固定于驅(qū)動(dòng)器之中，也就是說(shuō)，硬盤(pán)和硬盤(pán)驅(qū)動(dòng)器是一體的。將軟盤(pán)插入軟盤(pán)驅(qū)動(dòng)器時(shí)要注意方向,3.5英寸盤(pán)在插入時(shí)應(yīng)該使轉(zhuǎn)軸面向下，金屬片朝前，聽(tīng)到驅(qū)動(dòng)器口下方的彈出按鈕"喀噠"一聲彈出，說(shuō)明軟盤(pán)插好了。
取出時(shí)，應(yīng)該先按一下彈出按鈕，軟盤(pán)會(huì)自動(dòng)彈出一部分，接著將軟盤(pán)抽出。時(shí)下，使用5.2英寸盤(pán)的人越來(lái)越少，計(jì)算機(jī)上已很少安裝5.2英寸軟盤(pán)驅(qū)動(dòng)器。 值得注意的是，軟盤(pán)驅(qū)動(dòng)器的上方或下方有一個(gè)小小的指示燈，當(dāng)指示燈亮?xí)r，說(shuō)明計(jì)算機(jī)正在讀或?qū)戇@個(gè)驅(qū)動(dòng)器內(nèi)的軟盤(pán)，硬盤(pán)驅(qū)動(dòng)器的指示燈也位于主機(jī)箱前面板上，指示燈亮?xí)r，表明計(jì)算機(jī)正在讀或?qū)懹脖P(pán)。
驅(qū)動(dòng)器指示燈亮?xí)r，不能取出相應(yīng)驅(qū)動(dòng)器內(nèi)的軟盤(pán)或關(guān)機(jī)，否則可能會(huì)對(duì)磁盤(pán)造成損壞。
一臺(tái)計(jì)算機(jī)可能有不止一個(gè)軟、硬盤(pán)驅(qū)動(dòng)器，怎樣區(qū)別它們呢？我們采取給驅(qū)動(dòng)器取名字的辦法。驅(qū)動(dòng)器的名字都是用單個(gè)的英文字母表示的，用A和B來(lái)表示軟盤(pán)驅(qū)動(dòng)器，用C、D、E來(lái)表示硬盤(pán)驅(qū)動(dòng)器，光盤(pán)驅(qū)動(dòng)器一般用字母H來(lái)表示。這樣，就有了我們常說(shuō)的"A驅(qū)、B驅(qū)、C驅(qū)、D驅(qū)"，每臺(tái)計(jì)算機(jī)一般只有一個(gè)光盤(pán)驅(qū)動(dòng)器，所以經(jīng)常簡(jiǎn)稱(chēng)之為"光驅(qū)"。
