8 Track Tapes

Stereo 8, commonly known as the 8-track cartridge, 8-track tape, or 8-track, is a magnetic tape sound recording technology, popular from the mid-1960s to the early 1980s. Stereo 8 was created in 1964 by a consortium led by Bill Lear of Lear Jet Corporation, along with Ampex, Ford, Motorola and RCA Victor Records. A later quadraphonic version of the format was known as Quad 8 or Q8.

The popularity of 8-track cartridges grew from the booming automobile industry. In September 1965, Ford Motor Company introduced dealer-installed 8-track players as an option on most models and RCA Victor introduced 50 Stereo-8 Cartridges of pre-recorded music from their label of artists. By 1966, all of their vehicles offered this upgrade.

The format gained steady popularity due to its convenience and portability. Home players were introduced in 1966 that allowed consumers to share tapes between their home and portable systems. "Boombox" type players were also popular. With the availability of cartridge systems for the home, consumers started thinking of 8-tracks as a viable alternative to vinyl records, not only as a convenience for the car. Within a year, prerecorded releases on 8-track began to arrive within a month of the vinyl release. 8-track recorders had gained popularity by the early 1970s.

Problems with 8-track cartridges included an audible pause and mechanical click when programs were switched, due to the mechanical action of the device and the presence of a length of metallic foil, which a sensor detects and signals the end of the tape and acts as a splice for the loop. Among audio service technicians, there used to be a joke that "the 8-track is the only audio device which knocks itself out of alignment four times during each album."

Stereo 8 tapes and players developed a reputation for unreliability, due mostly to splice failures and the phenomenon of the player "eating" the tape. In the U.S., 8-track cartridges were phased out of retail stores by late 1982.

EOQ Calculations in Excel

Image
Last week in Operations Management we used Excel to calculate the Economic Order Quantity and graph Carrying Costs, Ordering Costs, and Total Costs. The Economic Order Quantity or "EOQ" is the order size that "minimizes" Total Costs. Any more or less and you are spending too much on ordering or too much on keeping inventory. For example, in the Excel spreadsheet below, if you had an Annual Demand of 12000 units, Ordering Costs of $10 per order, and Holding costs of $4 per unit per year, the EOQ would be 245 units and Total Costs would be $980.00: We used the following formula in Excel to calculate EOQ: =SQRT((2*B2*B3)/B4) And the following formula to calculate Total Costs at this point: =$B$6/2*$B$4+$B$2/B6*$B$3 To create the graph, we used the following formulas and simply copied them over a range of 100 to 500 units. Ordering Costs: =$B$2/D2*$B$3 Holding Costs: =D2/2*$B$4 Total Costs: =F2+G2 Looking at this chart, we can clearly see that our order size of 245 is

Reliability Calculations in Excel

Image
In Operations Management today we used Excel to calculate product reliability. Reliability is defined as "the ability of a product, service, part, or system to perform its intended function under a prescribed set of circumstances" (Stevenson, 2009). In order to calulate reliability over a given length of time we need to use the following formula: P(no failure) = e -t/MTBF where: e = 2.7183 t = Length of service before failure MTBF = Mean Time Between Failures One of the cases we did in class involved an auto detailing company that wanted to calculate the reliability of its vacuum cleaners. Excel provides an "EXP" funtion that we can easily apply here. After entering all data for the problem as shown on the spreadsheet below, we type the formula =EXP(-A5/$B$2) in cell B5 and copy down. Next we plot the distribution for t=0 to the maximum life expectancy of 20 years using a line graph. What we end up with looks like a classic case of "ex

“How Are We Doing?” Efficiency, Utilization, and Productivity

Image
In business, knowing how we are performing in relation to our competition is vital. Internally we want to know if we are using resources effectively and getting the most out of what we have. Efficiency and Productivity are two calculations that are fundamental to the success of any organization. While the calculations are simple, choosing what measures to use and collecting the necessary data requires a thorough understanding of your industry. To calculate Efficiency you will have to first decide what to use as a base for comparison. Does your company already have a “target” of some kind? Like total units produced? If so then you can compare everything to that. Once you have that, there are a couple of basic formulas that can be used: Efficiency = Actual Output/Effective Capacity X 100% Utilization = Actual Output/Design Capacity X 100% Design Capacity is the maximum output achieved under ideal conditions. Effective Capacity is always less than Design Capacity because of factors
