Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
An instrument for recording index markers, sector markers, addresses and the like, in selected tracks of a rotating magnetic memory, and which comprises: read amplifier means, write amplifier means, terminal connectors for connection to selected read and write heads of the aforesaid memory; at least one circuit card having logic circuitry thereon representative of a particular logic pattern; and control circuitry interconnecting said read and write amplifier means, said circuit card and said terminal connectors for controlling the transfer of data therebetween.
Claim 2
Dependent Claim
82 words
An instrument for recording index markers, sector markers, addresses and the like, in selected tracks of a rotating magnetic memory, and which comprises: read amplifier means, write amplifier means, terminal connectors for connection to selected read and write heads of the aforesaid memory; at least one circuit card having logic circuitry thereon representative of a particular logic pattern; and control circuitry interconnecting said read and write amplifier means, said circuit card and said terminal connectors for controlling the transfer of data therebetween.
Claim 3
Dependent Claim
59 words
The instrument defined in claim 1, and which includes a counter circuit, and a display means connected to said counter circuit for displaying the count thereon, and which includes a function switch connected to said counter circuit and to said control circuitry for selectively connecting said counter circuit in circuit with said read amplifier to perform a count function.
Claim 4
Dependent Claim
34 words
The instrument defined in claim 2, and which includes a pattern switch connected in circuit with said control circuitry selectively to determine the type of count function to be performed by said counter circuit.
Claim 5
Dependent Claim
69 words
The instrument defined in claim 1, and which includes delay logic circuitry, and a function switch connected to said delay logic circuitry and to said control circuitry for selectively connecting said read amplifier means to one track of the rotating magnetic memory so that data on said first named track may be copied onto said second named track with a predetermined delay, as established by said delay logic circuitry.
Claim 6
Dependent Claim
29 words
The instrument defined in claim 4, and which includes a write delay control connected to said logic delay circuitry for establishing the dealy exerted thereby on the aforesaid data.
Claim 7
Dependent Claim
50 words
The instrument defined in claim 1, and which includes a function switch connected to said control circuitry for selectively connecting an origin pulse source to said write amplifier means to cause said write amplifier means to write an origin pulse on one of the tracks of the rotating magnetic memory.
Claim 8
Dependent Claim
35 words
The instrument defined in claim 6, and which includes a switch connected in circuit with said function switch to cause said origin pulse to be written in the aforesaid track when said switch is actuated.
Claim 9
Dependent Claim
25 words
The instrument defined in claim 6, and which includes control means connected to said function switch for establishing said Origin pulse at a particular width.
Claim 10
Dependent Claim
26 words
The instrument defined in claim 1, and which includes a function switch for selectively connecting said logic circuitry on said logic card to said control circuitry.
