Ranges list the records to read. After the argument ranges are processed, input records are read. Input records have additional ranges to process. With feedback it is possible to implement search engines using binary search and hashed searches. Read physical blocks from a minidisk.

After the argument ranges are processed, input records are read. Input records have additional ranges to process. Using this driver in a feedback loop it may be possible to recover the contents of a broken minidisk. The input and output records are bit streams. A record is written for each input record.
