    No CD can hold 4GB of data.
    His CD might be carrying highly compressed data which on decompression may become 4GB.

    there is no possibility of linking or optimization..........

    i think CD's can be specially designed to carry that much data.

    Becoz Lata Mangeshkar was gifted with a CD containing all her songs on her Birthday.

    Then how come that CD contain that much songs???

    N that time, there were no DVD's.

    One thing, it was said that the disc was read by a CD drive.
    Secondly, the Mini DVD-r used in handycams cannot contain 4GB.
    Correct me if wrong.

    4 GB !!!How is it possible.

    I have 2 normal cds ,data is compressed in such manner that after extracting it becomes nearly 1.5 GB each but 4Gb is too much and also u r saying these cd's are mini size.

    @Akhil Jain
    Have u seen or checkd it ?
    u r friend may be just fooling!!!

    it cannot be read by a cd rom
    the guy HAS to be mistaken
    a mini cd contains max of 210 mb of data ..
    the same size dvd contains a few gb's im not sure how much

    but under no case is it a cd ... even with overburning option

    remember we arent talkin abt windows 3 in 1 which have common files hence multiple links which give cd capacity as 3.14 gb
    we're talkin abt a handycam that writs straight on optical media

    hence 4gb on a mini cd is OUT of the question

    btw miniDVD ram disks are capable of 2.92 gb of data
    miniDVD are 1.47gb in capacity
    and mini-DVD is used to describe cds with dvd data on them

    1. Did you mean Win 3.1? Otherwise pl explain what is Win 3in1.
    2. and mini-DVD is used to describe cds with dvd data on them. Is it correct? If so how can it contain 1.47 GB?
    Sorry if I am idiotic.

    the cd is some local brand termed as hd-cd

    (high definition cd)

    i have checked it

    it contains 4 gb and it is multi session

    nero showing 200 mb available capacity

    softwares on it are nero ,norton ,games


    no chance of cross linking data as in 3in 1 window cd

    he says it cost him 25 bucks


    it is being read by my lg cd writer

    though the speed is very slow
