Okla. Stat. tit. 18, § 1069
Any records maintained by a corporation in the regular course of its business, including its stock ledger, books of account, and minute books, may be kept in, or be in the form of, punch cards, magnetic tape, photographs, microphotographs, or any other information storage device, provided that the records so kept can be converted into clearly legible written form within a reasonable time. Any corporation shall so convert any records so kept upon the request of any person entitled to inspect the same. Where records are kept in such manner, a clearly legible written form produced from the cards, tapes, photographs, microphotographs or other information storage device shall be admissible in evidence and shall be accepted for all other purposes, to the same extent as an original written record of the same information would have been, when said written form accurately portrays the record.
