Hi All I am looking to buy a new PC and on the spec it talks about optical drive can anybody tell me what this is Do I need to buy it separate or not. It is from comet and in the ad is says Optical drive Plays & records CDs and DVDs Choose an optical drive that suits your needs. CDs are great for albums, DVDs are great for large data back-ups and movies. Look for Blu-Ray and HD DVD drives which are the latest technology and give far more storage - great for high definition content & data back-ups 2nd optical drive Not featured Cheers Graham
