Abstract: A trolling diver has a release arm which is hingedly connected to a plate. Mounted to the plate is a catch assembly. The catch assembly secures the release arm in a loose manner, between a first panel and a second panel, until triggered by a fish bite. A thru-hole of the release arm receives a first and second retaining member. The retaining members are loosely positioned into the thru-hole, allowing for the plate to realistically flop about within the catch assembly. The release arm is released from the catch assembly when a lure is triggered by a fish strike, resulting in the release arm rotating away from the catch assembly. The outboard lure attachment hole increases leverage and decreases the requisite force to trigger the release arm. Once released, the entire diver pulls thru the water with very little friction, allowing for easy retrieval of a hooked fish.

Abstract: A system of and method for writing and reading data on magnetic tape records having the capability of searching for certain data files in which selected messages are written is disclosed. The files are written successively on the tape with a name block which identifies or describes the files and data block which constitute the files written alternately to constitute the file format. The file names are written at much less than the normal data density. When reading the files, search operations are carried on at high tape speed; the ratio of the high tape speed to normal tape reading speed being the same ratio as the ratio of the normal density of recording of the data block to the lower density of recording of the file names in terms of bits per linear inch. The bit rate produced while reading the file names at high speed is then exactly equal to the bit rate generated while reading data blocks at low speed.
