Reading and writing a header and record on tape
First Claim
1. A computer implemented method for reading a record on a storage device, the method comprising:
- initiating, by a processor, a bypass mode, wherein the bypass mode enables the reading of a compressed record absent a data decompression operation;
reading, by a processor, the compressed record, wherein tape metadata corresponding to the compressed record is collected;
generating, by a processor, a header corresponding to the compressed record;
converting, by a processor, the collected tape metadata to a header information, wherein the header information is stored in a header;
adding, by a processor, the header information corresponding to the collected tape metadata to the header; and
providing, by a processor, the header and the compressed record to a host.

Abstract
As disclosed herein, a computer implemented method for reading a record on a storage device includes reading, by a processor, the record from the storage device, and generating, by a processor, a header corresponding to the record. The method further includes adding, by a processor, header information corresponding to the metadata to the header, and providing, by a processor, the header and the record to a host. Also disclosed herein, a computer implemented method for writing a record on a storage device includes receiving, by a processor, a header and the record from a host to be written to the storage device, and determining, by a processor, metadata included in header information corresponding to the header. The method further includes determining, by a processor, a write behavior specified by the metadata, and writing, by a processor, the metadata and the record to the storage device according to the write behavior.

15. A computer program product for reading a record on a storage device, the program product comprising:
-
one or more computer readable tangible storage media and program instructions stored on the one or more computer readable storage media, wherein the one or more computer readable tangible storage media are not transitory signals per se, the program instructions executable by a computer to perform; initiating, by a processor, a bypass mode, wherein the bypass mode enables the reading of a compressed record absent a data decompression operation reading, by a processor, the compressed record, wherein tape metadata corresponding to the compressed record is collected; generating, by a processor, a header corresponding to the compressed record; converting, by a processor, the collected tape metadata to a header information, wherein the header information is stored in a header; adding, by a processor, the header information corresponding to the collected tape metadata to the header; and providing, by a processor, the header and the compressed record to a host. - View Dependent Claims (16, 17, 18)
