Conversion is 100% of our business, and we do it expertly!

Do You Need Data Recovery or Data Conversion?

We have found that many people search for "data recovery" when what they need is media or data conversion.  Here's the difference:
 

Data Recovery

Data recovery is the process of trying to salvage data from a damaged tape or disk.  The damage could be physical, such as a crease in the tape, or magnetic, such as an unreadable area or partially overwritten data, but the key is that it is damaged in some way and unreadable by normal methods.  Such media is most commonly from a drive that you own, and the problem is not that you don't have the right drive, but that the drive can't read the tape.  In this case, you need data recovery.  The data recovery process will normally give you back readable data on the same kind of tape.  DISC does not provide data recovery services.
 

Data Conversion and Media Conversion:

If you have an undamaged tape or disk and you can't read it either because you don't own that kind of drive, or because it is written in a format that your computer doesn't understand, then you need media conversion or data conversion, not data recovery.  Data and Media Conversion is what we do.
 

What DISC Does:

Disc Interchange Service Company, DISC, is a data conversion service bureau specializing in converting data from IBM mainframe and AS/400 computers to PCs, and from DEC (Compaq, HP) VAX VMS and Open VMS to PC.

If all you need is to copy the data, without change, to a different kind of tape, DISC can do that.  Or if you need to convert the data from IBM EBCDIC to ASCII and unpack binary fields, DISC can do that, too.  For information on our IBM services, please see IBM Data Conversion Services, and for information on our VAX VMS services, please see VMS Data Conversion Services on our other web site.

DISC converts files from virtually all VAX and Alpha VMS tapes, Open VMS tapes, and many types of VAX disks.  We convert tapes from almost all IBM mainframe computers, including zSeries, System/360, System/370, System/390, 3090, 9020, 3033, 3081, 4361, 4381, ES/900 and others, running operating systems such as z/OS, z/OS.e, z/VM, OS/360, OS/370, OS/390, TPF, MVS, DOS, DOS/VS, DOS/VSE, OS/VS, VM, VM/370, MTS, VSE, and nearly anything else that can write a tape!  We also support AS/400, running OS/400

We also convert IBM mainframe-like tapes from dozens of other computers, such as Amhdal, Apollo, Burroughs, CDC, Data General, DEC, GE, Hitachi, Honeywell, HP, NCR, NEC, Wang, and many more.
 

DISC converts data from the following types of computer tapes and disks:
