PHN 9818 6.7.1981 ABSTRACT: "A method of writing and reading sector-organized in- formation into and from a record carrier body, and device for performing the method". A description is given of a method and an associated device for the writing and reading of infor- mation into and from a record carrier body. The record carrier body is preferably made of a radiation-sensitive medium and comprises a servo track. The information is written in consecutively arranged sectors and is read directly after writing for the purpose of verification. A vector address is added to the amount of information to be written in a sector. A vector address of this kind indicates a previously inscribed sector of the record carrier body, said previously inscribed sector having -the property that the information has been correctly written therein. The added vector address enables the transfer of only the correctly written information to a user when the written information is read. The use of so-called "inter- leaving" during the inscribing of information in the record carrier body protects the information written against an error burst.
