A protection device for the optical recording/reproducing apparatus includes at least one cover, a front panel fixed to the cover at a front opening, and at least one blocking strip extending down from a front of the cover. A clasping portion defining a first clasping hole extends from a front of the cover. A first latch engageable in the first clasping hole is formed on the front panel. The blocking strip prevents debris of an optical disk from flying out and causing damage to the optical recording/reproducing apparatus.
